Abstract
A mathematic model developed for describing the methane pyrolisis processes in a low-size plasmatron setup. Calculations are compared with experimental results on pyrolisis products composition. The factors promoting the yield of useful products are estimated. If the exit reactor temperature is increased to 1500 -2000 K, this reduces the ethylene yield and increases the soot content with a minor increase in the hydrogen yield.
