Abstract

In a process for dehydrocyclization of C.sub.6 -C.sub.12 alkanes in the presence of steam and a bed of a catalyst containing a Group IIA or IIB metal aluminate and a Group VIII metal, an oxygen containing gas is injected into the catalyst bed. The results of the oxygen injection are the internal generation of heat, a lower required steam to hydrocarbon ratio, and increased yield of aromatics.
