Catalytic upgrading of refractory hydrocarbon stocks.

摘要

A process for catalytically upgrading refractory hydrocarbon charge stocks, such as coker gas oil, to premium products including gasoline, kerosine, diesel fuel and low sulfur cracking stock by catalytically hydrotreating said stock and cascading the hydrotreater effluent through a hydrocracking zone containing a catalyst comprising ZSM-5 type zeolite in combination with a metal hydrogenation/dehydrogenation component.
