A process for producing liquid fuels from heavy hydrocarbons such as residual oil in which the cracking temperatures are in the range of 800.degree. F. to 1200.degree. F., and the residence times are between 0.05 seconds and 0.50 seconds.

Low residence time catalytic cracking process

A process for producing olefins and gasoline from residual oil by thermally cracking a side cut fraction from a fractionation tower, quenching the cracked product with residual oil, producing coke from a portion of the quenched product and using a portion of the coke to provide reaction heat for the thermal cracking.

Olefin production from heavy hydrocarbon feed

A process for pretreating residual oil by thermal regenerative vaporizing and pretreatment at short residence times and catalytically cracking the pretreated effluent from the thermal regenerative pretreatment process.

Hydrocarbon pretreatment process for catalytic cracking

A process for cracking heavy hydrocarbon feedstocks by separation into light and heavy fractions and concommitantly thermally cracking the light fraction and coking the heavy fraction.
