ABSTRACT:
Titanium-iron alloys, conditioned or activated to be reversible hydride formers, function as catalysts to promote gas phase hydrogenation and, dehydrogenation reactions. In the hydride form in the presence of hydrogen, the alloys catalyze hydrogenation of C.tbd.C, C.dbd.C, C.tbd.O, C.dbd.O, C.dbd.N, C.tbd.N, N.dbd.O, N.dbd.N and N.tbd.N bonds. Of particular utility is the synthesis of ammonia from a hydrogen-nitrogen mixture at relatively low temperature and pressure. In the unhydrided or metallic form the alloys dehydrogenate C--C, C.dbd.C, C--H and C--N bonds where hydrogen is attached to these groups. Of particular utility is the dehydrogenation of ethane to form ethylene at relatively low temperature and where increased pressure increases the percentage of ethane converted to ethylene.
