  • Catalytic cracking of hydrocarbon oils from two mixtures boiling above the gasoline range
    Patent number: 4620920
    Abstract: This invention concerns a process for the preparation of a gasoline boiling hydrocarbon from a mixture of hydrocarbons specifically defined. The hydrocarbon feedstock is a mixture of two hydrocarbon oils with the first hydrocarbon oil having a Conradson carbon test value C.sub.1 and % w such that the quotient of C.sub.1 /R is higher than 0.8 and a second hydrocarbon oil having a Conradson carbon test number C.sub.2 such that the quotient C.sub.2 /R is lower than 0.2 wherein R is equal to the reactor carbon requirement for the particular catalytic cracking unit and is between 3 and 8 percent by weight.
