Pure hydrogen and nitrogen gases are mixed in the appropriate proportion, heated to between 450°C; and 600°C;, compressed to about 1,000 atmospheres pressure, and passed over a catalyst. The reaction is 3H2+N2[right pointing harpoon over left pointing harpoon] 2NH3+heat. The ammonia gas is liquefied by rapid cooling; unreacted nitrogen and hydrogen are returned to the reaction chamber.
