Abstract
Catalytically cracked naphthas containing C.sub.9 + hydrocarbons are hydrocracked over a crystalline zeolite, typically, mildly steamed zeolite beta then subjected to reforming to achieve a gasoline product of reduced end boiling range and higher octane than the feed. A hydrogen stream from the reformer which contains a catalytic promoter, such as chlorine, is separated into a first stream and a second stream. The first stream is treated over a solid sorbent to remove the promoter and recycled promoter to the hydrocracking step while the untreated second hydrogen stream which contains promoter is recycled to the reformer.
