Regeneration of dehydrocyclodimerization catalyst

Patent ·
OSTI ID:6331644
; ;
A process is described for the dehydrocyclodimerization of hydrocarbons which comprises contacting a feed stream containing aliphatic hydrocarbons with a catalyst, under dehydrocyclodimerization conditions, where the catalyst is comprised of phosphorus-containing alumina, gallium, and a crystalline aluminosilicate having a silica to alumina ratio of at least 12. The catalyst becomes deactivated as a result of the dehydrocyclodimerization reaction, and the deactivated catalyst is regenerated by contacting the deactivated catalyst with an oxygen-containing regeneration gas at catalyst regeneration conditions.
