Coherent properties of diffraction-free pseudo-Bessel optical beams propagating in a turbulent atmosphere are theoretically studied. The solution of the equation for the second-order transverse function of mutual coherence of the optical radiation field, derived from the paraxial approximation of the scalar wave equation, is analyzed. The behavior of the modulus and phase of the complex coherence degree, the coherence radius, and the integral scale of the coherence degree of a Bessel-Gaussian optical beam and a conic optical wave found through conic focusing of an optical beam by an axicon is studied for different parameters of the optical beam and turbulent atmosphere. Significant qualitative and quantitative differences are discovered between the studied coherence characteristics of a Bessel-Gaussian optical beam and a conic optical wave. In general, the coherence of a conic optical wave is higher than that of a Bessel-Gaussian optical beam under identical propagation conditions in a turbulent atmosphere.

The coherence length and the degree of broadening of a laser beam under the action of turbulence are estimated from the results of remote acoustic sounding of the atmospheric boundary layer with the Volna-4M sodar. The daily average profile of the coherence length in different seasons is considered. Corrections to the effective radius of a laser beam due to turbulence and the monthly average values of these corrections are calculated. A noticeable excess of the possible broadening of the laser beam in winter above that in summer is revealed.

The effect of “photonic nanojet” (PNJ) arising in the near-field scattering region on the surface of dielectric axisymmetric microparticles (hemisphere, axicon, and combined particles) under optical illumination is theoretically considered. Key PNJ parameters (length, width, and peak intensity) are numerically calculated using the method of discrete-dipole approximation; the dependence of these parameters on the geometric shape of microparticles is analyzed. We show that the use of a special type of combined transparent particles, which consists of an axicon and two attached hemispheres, allows ultra-localized light fluxes with a peak intensity considerably exceeding the corresponding values for particles of simple shapes (hemisphere and axicon).

The volume fraction of filling of the region of multiple filamentation, formed during propagation of femtosecond laser radiation at 800 and 248 nm wavelengths in air, by plasma formations is studied on the basis of the numerical solution of the nonstationary nonlinear Schrödinger equation. It is ascertained that this fraction for l = 248 nm more than twice exceeds the corresponding values for l = 800 nm and can exceed the percolation threshold in terms of the level of plasma density required for occurrence of breakdown.

The results of lidar investigation of wind turbulence in the presence of low-level jet (LLJ) in the atmospheric boundary layer are presented. From the measurements by Stream Line lidar at the Basic Experimental Complex of IAO SB RAS and on the coast of Lake Baikal, different turbulence parameters inside LLJ were estimated. It is ascertained that the turbulence is very weak in the central part of LLJ. In particular, the turbulence kinetic energy does not exceed 0.1 (m/s)². The turbulent energy dissipation rate and turbulence integral scale within a jet stream were quantitatively estimated from lidar measurements with a relative error of no more than 12% for the first time. According to these measurements, a dissipation rate of about 10^-5 m²/s³ is characteristic. From the lidar measurements on the coast of Lake Baikal, the turbulent energy dissipation rate in the lower part of a jet stream exceeds the corresponding value in the upper part of the LLJ by 1 to 2 orders of magnitude. In the central part of LLJ, the turbulence integral scale averages about 100 m, which is 2-3 times lower than the effective thickness of the jet stream.

The method of maximum of function of accumulated spectra (MFAS) has been used for the first time to estimate the wind velocity from measurements with a micropulsed coherent Doppler lidar (MPCDL) during conical scanning with a probing beam. It is ascertained in an experiment with a Windcube 200s MPCDL that MFAS allows an increase in the maximum altitude of retrieval of the vertical profiles of the wind speed and direction by 30% on the average in comparison with the filtered sine-wave fitting.

The spatiotemporal variability of temperature in the atmospheric boundary layer has been studied comparatively in the city of Tomsk (Russia) and in the coastal zones of Lake Baikal and Lake Issyk-Kul. Measurements with an MTP-5 temperature profiler have shown that the conditions of thermal stratification of the lower 1-km air layer strongly differ in summer under urban conditions in the absence of large water reservoirs nearby and in the mountain areas on the coasts of big lakes. The types of stratification and parameters of the atmospheric boundary layer in the regions under study are detsermined.

The article views a problem of establishing ground transportation that connects Sakhalin Island to mainland Russia through the prism of history: from the imperial era to the present day where the Sakhalin-Mainland railway project is interpreted as a breakthrough component in the strategy of strengthening Russia’s trade and economic ties with Asia-Pacific and, above all, Japan. We emphasize that the project cannot be cost-effective if it is confined to building a bridge or a tunnel across the Nevelskoy Strait and focuses only on the Sakhalin Railway. It is also necessary to incorporate a bridge across the La Perouse Strait in the project, which will provide access to the Japanese railway network and allow container traffic from Japan to Europe via Russia. With this approach, the Sakhalin-Mainland federal project becomes international, and its successful implementation will not only meet the project’s economic objectives but also solve Russia’s political and military strategic problems in the Pacific.

Studies show that the share of the shadow economy in Russian regions varies between 11 and 85 percent. Large economic differentiation at the regional level keeps the problem of choosing methods for measuring the shadow economy current. While there is a fairly large number of studies on measuring the shadow economy at the country level, it is not enough at the regional one. Moreover, it is impossible to use all methods for the regional level without adjusting. The article considers methods of measuring the shadow economy through the prism of their potential applicability to evaluating the hidden gross regional product. We point out that the most often used methods for measuring the shadow economy at the regional level are the balance, the electricity consumption, and the MIMIC methods. The monetary method appeared to be not applicable at the regional level; the method of fuzzy sets was not applied to regions but has a high potential if the internal evaluation mechanisms are fundamentally refined.

Based on extensive experience in modeling the economy of the regions and in experimental calculations for forecasting economic development, the article determines the real area of use of interregional input-output models and defines approaches to bring existing scientific instruments closer to the solutions of relevant applied problems. The current economic and mathematical models limit the possibilities of theoretical modeling but allow obtaining the forecasts that experts need at present. From experience gained, the latest modifications of interregional input-output tools provide forecasts for the economic development in material and financial composition, not only maintaining compliance with the classical principles of economic theory, but also fixing new provisions on the possible obtaining of numerical values of the national economic efficiency and agreeing them with the commercial efficiency of manufacturing industries.

The article presents a methodology for assessing food sovereignty and food security as exemplified by agro-industrial production in the Siberian Federal District. The assessment of food sovereignty rests upon the official market basket and corresponding consumption patterns approved by the Russian Government, as well as the population size. Official per capita food cons sumption patterns are determined in physical and value terms, regarding the prevailing market prices. We identify the total costs for all food products and compare them with the actual average per capita spending on groceries. In general, food self-sufficiency is not provided if expenses are equal to or greater than the total cost of food products. We show that a social eco-economic system engaged in food production experiences external threats and natural hazards, which leads to risks and losses and, ultimately, changes the system performance indicators. Relying on the methodology designed, the article assesses the level of food self-sufficiency and food security for the SFD population and considers issues of state support and regulation.

The article analyzes the actual amount of food consumed by the northern Russian population in comparison with rational norms and national averages. We examine the differences in staple food consumption among the northern regions using the following statistical characteristics: mean value, range of variability, coefficient of skewness, and kurtosis. We identify that the inhabitants of the North under-consume certain food groups relative to the proposed standard. Their diet lacks complex carbohydrates, plant foods, eggs, and dairy products. The article establishes that the northern regions are characterized by asymmetric food consumption development, with increasing differences between regions rich and poor in mineral resources. We show that at present, the population of the North is largely limited in receiving proper nutrition by economic accessibility. We propose, on the one hand, to develop guidelines on rational nutrition for the northern population considering extreme environmental conditions and, on the other, to ensure the physical and economic accessibility of the recommended product set.

The work is devoted to studying child and adolescent primary morbidity dynamics in the Russian Federation with Rosstat data. It is important to separate this age group out since its morbidity not only characterizes the current situation but also makes it possible to predict the state of health of the entire population in the future. We put major emphasis on child and adolescent morbidity in the Siberian Federal District as the most problematic in terms of health and population morbidity per basic classes of diseases. A significant place in the study is given to morbidity along the classes of diseases that make the main contribution to the younger generation mortality. The peculiarity of the methodological approach to the research is that, unlike the numerous works characterizing the physical condition of certain child and adolescent groups in a variety of territorial objects, this study estimates the morbidity from the position ofpublic health and demographic potential formation. It is shown that there was a significant deterioration in the health of the younger generation, expressed in a high incidence rate; and this incidence rate was well ahead of that in adults. In the Siberian Federal District, the growth rate of child and adolescent morbidity was above the national average.

The article suggests an approach to verifying the results of genuine savings assessment in regions based on econometric modeling. It describes a methodology for calculating the components of genuine savings regarding the existing statistical accounting system and evaluates the sustainable development of Siberian regions over the past ten years. We design a model to link genuine savings and future consumption. Having evaluated the model, we confirmed two hypotheses: first, genuine savings growth leads to an increase in the future well-being; secondly, the components of genuine savings are estimated correctly. Therefore, based on the proposed approach to assessing genuine savings, it is possible to formulate a methodology for calculating them as an indicator in the statistical accounting system of Russia, at which point the indicator can be included in the national program of following the principles of sustainable development as one of the sustainability indicators for decision-making in regional policy.

The key task of the State plan for the Development of Gas and Petrochemical Industry in Russia for the Period up to 2030 (Plan-2030) is the search for constructive forms to coordinate the strategic interests of extracting companies in new oil and gas provinces of the Russian East with the interests of participants in the projects aimed at creating the East Siberian and Far Eastern gas/petrochemical clusters. The article assesses strategic interests of Gazprom PJSC, Sibur PJSC and Rosneft Oil Company PJSC by analyzing their corporate strategies. We propose a methodical approach to designing a scheme for the formation of various strategic alliances among companies with the network and imitation models of the investment program of the East Siberian Oil and Gas Complex megaproject. The article carries out a scenario analysis to test the efficiency and risks related to consolidating free profits from extractive industries used to create gas chemical clusters. Through the example of the project for the Amur gas chemical complex, we estimate possible risks of Sibur allying with Gazprom and Rosneft extracting companies.

Drawing from the data on the home buyers ’ addresses, we estimate the purchasing activity of Russians in the primary real estate market of Moscow metropolitan area (MMA) and compare it to their labor migration activity. The objects of analysis are 149 cities and 80 «rests of regions». This article is the first ever to examine the peculiarities of migration and investment behavior with differentiation between cities and rural areas, between size classes of settlements and individual large cities. Thus, the paper makes it possible to fill a gap in assessing the mobility of the factors ofproduction, namely capital and labor. We reveal a sharp contrast between settlements of different sizes in terms of how they interact with the metropolitan agglomeration. The bigger the settlement, the less is the intensity of labor migration to the capital; the intensity is decreasing in a rapid and monotonous manner. The activity of foreign buyers depending on the population of the city where they reside varies non-monotonously, with a maximum for cities with a population of250-500 thousand people in the real estate market of Moscow and 100-500 thousand people in Moscow Oblast. For MMA, small towns and rural areas (except for Khanty-Mansi and Yamal-Nenets Autonomous Areas) are a source of labor resources while their buying activity in the real estate market is weak. Cities with a population of over one million practically do not create an inflow of labor migrants and show moderate activity in the Moscow real estate market. Moscow Oblast interacts through labor migration and housing acquisitions with smaller settlements than the «premium» real estate and labor markets of Moscow. The attraction of Moscow Oblast is rapidly decreasing with distance, extending to the first- and second-order neighbors, while Moscow’s influence spreads throughout the country.

The article examines the use of economic instruments for water resources management in the Republic of Buryatia and gives recommendations for their improvement. The research methodology is based on an integrated approach, analysis of instruments to meet the goals ofwater policy, complete its objectives, and satisfy efficiency criteria. We identify the development problems of the water sector and the main economic instruments to regulate its operation. It is concluded that the instruments used are ineffective and poorly comply with the goals and objectives of water policy and socioeconomic development policy of the Republic of Buryatia. We show ways to improve instruments for water resources management.

The paper is concerned with the current trends and further prospects in the field of household solid waste (HSW) in the regions of Siberia with domestic and world experience. We demonstrate the weakness of the institutional environment that emerged in the sphere of HSW circulation. It is shown that the institutional environment is a key factor hindering the development of modern waste processing forms. We suggest an aggregated approach to scenario simulating of HSW circulation, the application of which allows obtaining estimates of the required capital investments for the Siberian regions. The endorsement of this approach indicates high requirements to the return on sales of secondary material resources and lack of incentives to invest in an increase of household solid waste processing, which significantly limits the effectiveness of government measures to reform the industry.

The article examines the experience of ethnological expertise in the Republic of Sakha (Yakutia) and assesses the performance of this institute for protecting the rights of indigenous small-numbered peoples of the North when carrying out major investment projects. It is the first to estimate damage mitigation for 1 square km of the land or water area withdrawn from the traditional economy per 1 member of the indigenous minority group. We compare compensation amounts with the annual incomes of community members, as well as with actual payments in other regions. We show the shortcomings of ethnological expertise and propose options for improvement. The article substantiates a need to expand the list of ecosystem services. A conclusion is that, when assessing damages in the event of worsening conditions for traditional economic activities, it is necessary to apply a different approach, namely an evaluation of the impact on community sustainability.

The main areas of its work include as follows: expounding on the theory of territorial production complexes; designing a methodology for forecasting and analyzing the development of problem regions; applied research of Russia’s spatial development based on interregional input-output optimization models; elaborating on the theory of spatial equilibrium and models of interregional economic interactions; analyzing and forecasting inter-level relations in the «na-ional economy-regions» system within Project SIRENA; measuring and forecasting spatial distribution of economic activity in Russia; modeling and applied studies on the socio-economic development of Siberia and the Russian North in the system of interregional input-output and level-to-level interrelations; analyzing the impact of institutional design on the proportions of national and regional spatial development.

For about 15 years, researchers of the Russian Federal Nuclear Center - All-Russian Research Institute of Experimental Physics (RFNC-VNIIEF) have performed studies of fast gas-dynamic processes using a proton radiographic system developed jointly with the Institute of High Energy Physics on the basis of an U-70 accelerator. The main advantages of flash proton radiography over widespread flash X-ray radiography are spatial resolution, multi-frame mode, transmission capability, dynamic range of recording, etc. In recent years, effort has continued to extend the capabilities of the proton radiographic system by increasing the total time and expanding the recording field and equipping it with additional diagnostic techniques and new explosion-proof chambers. In this paper, we present the results of studies that illustrate these capcbilities.

Experiments were performed to study the spherical compression of deuterium and helium to pressures of ≈3000 GPa in a quasi-isentropic regime. The process was recorded by a multi-frame radiographic system which produces up to nine X-ray images of a cavity with gas at various times in one experiment. X-ray images show that explosive devices provide a cavity shape close to spherically symmetric with gas up to the maximum compression of the gas. The experimental data are in good agreement with the results of calculations performed using the RFNC-VNIIEF equations of state of the gases studied. The results of these calculations are used to determine the parameters of the region of compressed gas states reached in the experiments: for deuterium, density 5.5 g/cm³ and pressure 3.6TPa; for helium, density 4.7 g/cm³ and, pressure 2.4 TPa.

This paper describes an experimental study of isentropic compression of a VNM-3-2 heavy tungsten alloy by a pressure of a superstrong pulsed magnetic field, induced by a magnetocumulative MK-1 generator. Experimental points obtained on a p- ρ-diagram of the alloy are compared with its cold compression curve, previously constructed on the basis of shock-wave experiments. The purpose of this study is to correct and clarify a state equation of the alloy under an ultrahigh pressure and low temperature. This equation is used to analyze data obtained in experiments on isentropic compression of various substances.

The structure of bismuth samples after shock-wave loading at pressures of 0.7-2.4 and 22-32 GPa was studied. Before loading, samples were at room temperature or heated to 230-240 ^oC. Loading by a pressure of 1.5-2 GPa at an initial temperature of 233-240 ^oC led to a structural change in bismuth, indicating melting of the sample in a shock wave. The time of shock-wave action was ≈0.7 μs.

Shock wave properties of porous specimens made on the basis of matrices composed of inert and chemically active media (silicon rubber and emulsion, which is an aqueous solution of ammonium nitrate with mineral oil and emulsifier) are studied. The porosity of the specimens is generated by using a filler composed of glass microspheres. The wave velocity profiles are measured by a VISAR laser Doppler interferometer. It is shown that the shock compressibility of porous silicon rubber at pressures below 0.1 GPa displays an anomalous behavior, resulting in smearing of the compression pulse front propagating over the specimen. In the emulsion matrices without microspheres, there are no noticeable chemical transformations up to the pressure of 15 GPa. Addition of microspheres drastically decreases the threshold of chemical reaction initiation and leads to the formation of a steady detonation wave.

Shock compressibility of porous specimens made of mixtures of micro- and nano-sized nickel and aluminum powders is experimentally studied in the pressure range up to 60 GPa. shock wave profiles in the specimens are recorded, and shock adiabats are determined. The equation of state of the specimens is derived within the framework of the Zel'dovich model. The shape of the shock wave profiles does not reveal any specific features that can be associated with a possible reaction between the species. The shock adiabats of the specimens of two types of powder mixtures coincide within the experimental error despite significantly different sizes of powder particles, which implies that either there are no noticeable chemical transformations or, vice versa, they are completed within the shock loading time. The predicted shock adiabat with the reaction between the species being ignored passes in an immediate vicinity of the experimental data, which testifies to the absence of the reaction.

This paper describes experimental results on using nonstationary spectrometry in a terahertz frequency range to determine the composition of gaseous products of decomposition of energy materials. Dependences of analytical signals on lines of the main products of ammonium nitrate and PETN decomposition on time are obtained.

A number of physical and chemical processes occurring under the action of a laser pulse in nanosized aluminum and aluminized explosives on the basis of fine-grained PETN and benzotrifuroxane along with estimates of the effect of aluminum of the dynamics of explosive transformation in these explosives conclude that it is possible to initiate aluminized explosives by laser radiation. The estimated and experimental results show that the main source of hot points capable of causing an explosive transformation in aluminized explosives under the action of a laser pulse can be a compression wave that forms as a result of rapid evaporation of asufficient number of aluminum particles. It is shown experimentally aluminized explosives based on fine-grained RDX and HMX can be initiated by a laser pulse whose source is no more powerful than that in the case of PETN and benzotrifuroxane.

A key issue for explaining bursts and explosions of high explosives (HEs) under low-velocity mechanical impacts with registered time delays is the formation of local high-temperature regions. It is demonstrated by an example of HMX that the required temperatures should significantly exceed the HMX melting point and can be obtained only due to the work of viscosity forces in the liquid phase. In this case, however, it is necessary to ensure HE flow velocities greater than the primary impact velocities by several orders of magnitude. A mechanism of generation of such velocities is proposed: squeezing of the HE, which is heated on shear strains and plasticized, from the shear layer under the action of the pressure difference along the layer. Conditions of fast decomposition of the HE in the shear layer and conditions of an explosion of the surrounding HE are formulated.

Particles are discharged from surfaces of materials under a shock-wave load. Experimental results on determining the minimal values of a specific weight of particles with which their velocity can be detected using a heterodyne interferometer (PDV method) are presented. An effect of multiple frequency shift of a Doppler signal in the case of laser radiation being reflected from surfaces of materials and a semitransparent layer of dust particles is described.

This paper presents the results of an experimental study of the particle ejection into a low (0.05 atm) vacuum with a narrow (0.2-0.8 mm) rough (Rz = 20-50 μm) surface of the lead sample under the action of a shock wave of intensity about 17 and 34 GPa. The flow was recorded with a video camera in a microscopic mode with a short laser illumination. Due to the small optical thickness of the dust flow, particle spectra approximately 80% of its height measured from the front of the flow were obtained. It was found that when the lead is in the solid state (17 GPa), s jets consisting of a lot of particles are ejected from the rough surface; when the lead is in the liquid state (34 GPa) a lot of thin (from 7 μm) microcumulative jets are ejected from the metal surface, which with time decay into particles.

A heterodyne interferometer is used (PDV method) to study a particle discharge from the free surface of lead samples of different roughness under a shock-wave load. In experiments, the velocity of the free surface of samples and the dust flow velocity are determined, and indicator foils and thin glasses are used to calculate the specific weight of the dust. Dependences of the specific weight of particles on their relative velocity are constructed. The effects of roughness and phase state of the substance after a shock-wave load on the possibilities to determine the velocity of the free surface and the specific weight of discharged particles using indicator foils. It is shown that, with given surface roughness, the specific weight of dust, discharged from the surface during lead melting under the action of a shock wave or load wave, is much larger than in a sample being in a solid state.

This paper described a piezoelectric method for measuring the density and mass of dust flows ejected from the free surface of a condensed material upon arrival of a shock wave at it and its implementation in the Russian Federal Nuclear Center - Institute of Experimental Physics (Sarov). Piezo sensors, methods of recording and signal processing are presented. Results of measurement of the density and mass of dust flows by piezoelectric, radiographic and protonographic methods, and method using indicator foils are compared.

The mass distribution along a flow of microparticles is measured by methods of synchrotron radiation from the VEPP-3 collider. The use of the soft spectrum of radiation allows microparticle flows to be measured with a record-beating (minimum) specific density (1 mg/cm³). Simultaneous recording of microparticle flows by piezo-electric sensors offers a possibility of comparisons and extension of results.

The paper describes a method of simultaneous measurements of kinematic parameters of a fast process by a microwave radio interferometer with a 3-mm range of wavelengths and the brightness temperature of the same process by the microwave radio interferometer operating in the radiometer mode. The methods of radiometer calibration and analysis of radiometric data are described. Results of experimental investigations are reported by an example of measuring the detonation velocity and estimating the brightness temperature of the detonation front in TNT.

A TKPF269 streak camera with mirror scanning and a photosensitive element based on a CMOS matrix were developed for the purpose of replacing film in high-speed cameras with mirror scanning (SFR-2M, USF-2, etc.). A brief description of a TKPF269 streak camera is given. The spatiotemporal picture of the emergence of light radiation from the ends of optical fibers upon firing of an explosive in a model assembly was simultaneously recorded by a TKPF269 streak camera and a USF-2 photo-recording camera to compare the metrological characteristics of these cameras. The results of experimental data processing are presented.

Currently, the computer simulation of the behavior of products containing explosives at various stages of their life cycle has become of increasingly greater importance. Computational methods have been verified by studying the propagation of a detonation wave in channels of model distributors using high-speed photography. This paper focuses on the motion of a detonation wave at the bends of the channel and the formation of dark areas. The results obtained using a NANOGATE 2000 optoelectronic system based on a NANOGATE 22 high-speed camera with a shooting frequency of up to 10⁹ frame/s are presented. The position of a detonation front moving with bends at an angle of 60, 90, and 120^oC was first visualized with an exposure time of 20 ns and an interframe interval of 80 ns.

Development of biocompatible coatings on implant surface is an essential and urgent problem. Coatings based on titanium oxynitride formed by means of reactive magnetron sputtering are used as the biologically inert material for surgical products. Oxynitride coatings are suitable for use under the conditions of long-term contact with biological liquids. The characteristics (corrosion stability, film solubility) of Ti-O-N coatings deposited on the substrates by means of reactive magnetron sputtering were investigated. The coatings and the compositions of model liquids formed as a result of the dissolution of titanium oxynitride films in physiological liquids were studied by means of infrared and gas spectroscopy, atomic emission analysis. It was established that the samples of Ti-N-O biocoating contain nitrogen, and the solutions contain nitrogen oxide NO, the molecule which is vitally necessary for living organisms.

Cu-Mo/ZSM-5 catalysts with Мо content 4.0 mass % and Сu 0.05 to 1.0 mass % were prepared by dry mechanical mixing of ZSM-5 zeolite with nanosized powders (NSP) of molybdenum and copper. To carry out comparative tests, Cu-Mo/ZSM-5 systems were prepared from 4.0 % Мо/ZSM-5 catalyst by impregnation with Cu(NO₃)₂ solution and mechanical mixing with copper oxide (CuO). The acid characteristics of thus prepared samples were investigated by means of temperature-programmed desorption of ammonia. The concentration and strength of the acid sites of the catalysts were measured. It was established that the addition of 0.1 % copper NSP to the 4.0 % Mo/ZSM-5 catalyst promotes a decrease in the concentration of strong acid sites to 140 mmol/g, while further increase in the fraction of copper NSP causes an increase in their concentration (to 153 mmol/g). The activity of the catalysts in methane conversion decreases in comparison with the sample containing 0.1 % Cu NSP. Methane conversion degree after reaction for 20 min with 4.0 % Мо/ZSM-5 and 0.1 % Сu-4.0 % Мо/ZSM-5 catalysts was 16.1 and 18.9 %, respectively. The effect of the temperature of methane conversion on its conversion degree in the presence of the 0.1 % Сu-4.0 % Мо/ZSM-5 catalyst was studied. It was demonstrated that temperature rise from 650 to 750 °С is accompanied by an increase in methane conversion. For instance, within the first 20 minutes of reaction at a temperature of 750 °C and 650 °C is 18.9% and 7.9% respectively. It was shown that the optimal feed space velocity of methane during its conversion over the 1.0% Cu-Mo/ZSM-5 catalyst is 1000 h^-1.
