  • Fluid catalytic cracking of heavy hydrocarbon oil
    Patent number: 4755283
    Abstract: A method of cracking a heavy hydrocarbon oil containing a residual fraction with a boiling point of 538.degree. C. or higher, including contacting the heavy hydrocarbon oil with a fluidized bed of a particulate composite catalyst which includes an amorphous refractory inorganic oxide and a crystalline aluminosilicate dispersed in the oxide and which has a surface area distribution such that the surface area of pores having pore diameters in the range of from three times to six times the average molucular size of the residual fraction is at least 60% of the surface area of pores having pore diameters in the range of 15-150 .ANG..
