Abstract
This paper presents experimental results for the thermal decomposition of hydroxylammonium nitrate (HAN) in the presence of activated carbon with a high specific surface (up to 3000 m2/g) obtained by activation of rice husk with potassium hydroxide at a temperature of 700oC in the rotating spherical furnace. With addition of activated carbon, the temperature of the beginning of the decomposition of HAN reduced from 185 to 86±0.5oC. The burning rate of HAN doped with activated carbon increases to 400 mm/s at an overpressure of 6 MPa. It has been shown that the addition of activated carbon reduce the amount of NO x gases produced by decomposition to 30%.
