Influence of activated coal on the thermal decomposition of hydroxylammonium nitrate

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 m$^2$/g) obtained by activation of rice husk with potassium hydroxide at a temperature of 700$^\circ$C 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 $\pm$ 0.5$^\circ$C. 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%.
