Abstract
Ammonia or cyanogen or both are produced by passing a mixture of nitrogen or air and carbon monoxide or hydrogen, or a hydrocarbon such as natural gas over a catalytic mass consisting of iron, cobalt, or nickel, an alkali, and an alkaline earth, first at about 1500-1900 DEG F. to render the mass active, and then at 600-1200 DEG F. When the activity becomes reduced, the temperature is again raised to restore it. The catalytic mass may contain iron in the metallic state or as oxide or carbonate; the alkali may be sodium or potassium oxide, hydrate, or carbonate or a salt such as acetate or oxalate; and the alkaline earth may be calcium, barium, or magnesium oxide. The mixture is preferably rendered plastic by adding water or a binder such as tar or molasses, briquetted, dried at 1200 DEG F., and crushed. A mixture of an alkali ferrocyanide and calcium or magnesium ferrocyanide may also be used. Ammonia is produced in the preliminary treatment when a ferrocyanide is employed.ALSO:Ammonia or cyanogen or both are obtained by passing a mixture of nitrogen or air with carbon monoxide or hydrogen, or a hydrocarbon such as natural gas, over a catalytic mass consisting of iron, cobalt, or nickel, an alkali, and an alkaline earth, first at a temperature of about 1500-1900 DEG F. to render the mass active, and then at 600-1200 DEG F.
