ABSTRACT:
Bi-metallic alloys of iron and titanium are employed as catalysts for reacting nitrogen and hydrogen to yield ammonia. The binary alloy composition is first activated by removing surface oxides with hydrogen gas at elevated temperatures and pressures. The particle size of the catalyst may then be reduced by one or more dehydriding and hydriding steps.
