FIELD: ammonia production. SUBSTANCE: method of ammonia production from hydrocarbon materials, steam and air includes compression and purification of hydrocarbon materials from sulfur compounds, steam and steam-air catalytic conversion of methane, conversion of carbon monoxide, cleaning of produced nitrogen-hydrogen mixture from oxygen-containing compounds, compression, synthesis of ammonia in closed cycle. In so doing, added to initial air is nitrogen and obtained mixture is directed for steam-air catalytic conversion of methane, with ratio of added nitrogen and air equaling 0.001-1.121. EFFECT: reduced specific consumption of hydrocarbon materials. 2 ex |
