摘要

"alkane dehydrogenation catalyst composition, process for dehydrogenating an alkane and process for at least partially reactivating an at least partially deactivated alkane dehydrogenation catalyst" a catalyst comprising a group iiia metal, a group viii noble metal, and an optional promoter metal on a catalyst support selected from silica, alumina, silica alumina composites, rare earth modified alumina, and combinations thereof doped with iron, with vib group metal, with vb group metal, or with a combination thereof, offers reduced reactivation time in air atmosphere compared to different identical catalysts. Reducing reactivation time can in turn reduce inventory and capital costs.
