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 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%.
Keywords:
