Gorring, R; Smith, R

A dual bed process for upgrading a refactory hydrocarbon feed, characterized by a bromine no. Greater than about 10 and an aromatics content of at least about 40 weight percent, which comprises contacting a stream of said feed initially in a hydrotreating zone containing a bed of hydrotreating catalyst under reaction conditions which include a pressure within the range of about 100/sup 0/ to about 1800 psig, a temperature between about 550/sup 0/F and about 850/sup 0/F in the presence of between about 2.4 and about 24 moles of hydrogen/mole of hydrocarbon charge to convert sulfur and nitrogen derivatives of hydrocarbon to hydrogen sulfide and ammonia; passing the entire effluent from said hydrotreating zone to a hydrocracking zone containing a bed of hydrocracking catalyst comprising a crystalline aluminosilicate zeolite characterized by a silica to alumina ratio of at least about 12 and a constraint index within the approximate range of 1 to 12 in combination with a metal component exhibiting hydrogenation-dehydrogenation activity under reaction conditions which include a pressure within the above stated range, a hydrogen concentration between about 2 and about 23 moles of hydrogen per mole of charge to said latter zone and a temperature between about 650/sup 0/F and about 950/sup 0/F and recovering gasoline of high octane number directly as a product of the aforenoted dual bed sequential operation.
