ABSTRACT:
The present invention provides a process for catalytic upgrading of refractory hydrocarbon charge stocks, such as coker gas oil, to premium products including gasoline, kerosene, diesel fuel and low sulfur cracking stock initially by catalytic hydrotreating and cascading the hydrotreater effluent, through a hydrocracking zone, without change in the pressure of the system, containing a catalyst which is characterized by a crystalline zeolite having a silica/alumina ratio greater than 12 and a constraint index of 1 to 12.
