Fremgangsmåte til dehydrogenering av lette alkaner

摘要

In a process for dehydrogenating alkanes containing 2-5 carbon atoms per molecule in the presence of steam and a catalyst composition comprising IIA and/or IIB metal aluminate, a noble metal and a Group IVA metal oxide the improvement comprises the step of contacting the catalyst composition, after it has been oxidatively regenerated, with a reducing gas comprising free hydrogen and steam.
