摘要： A process which comprises recracking a cracked naphtha feed containing up to about 60 percent, suitably from about 20 to about 40 percent olefins, over a crystalline aluminosilicate zeolite catalyst to further crack the naphtha and saturate at least about 50 percent of the olefins, preferably from about 90 percent to about 100 percent of the olefins, based on the weight of said cracked naphtha feed. In a preferred combination a gas oil is catalytically cracked in a first stage to produce a cat cracked naphtha product of high olefin content, and an intermediate boiling component thereof is recracked as a feed in a second stage over a zeolite catalyst to saturate the olefins, and hydrodenitrogenate and hydrodesulfurize said cat cracked naphtha. The recracked cat cracked naphtha is then hydrotreated at low to mild severities and then catalytically reformed (hydroformed) to produce high octane gasoline.
