Abstract
A process for upgrading topped crude oils and residual portions comprising material boiling above 552.degree. C. (1025.degree. F.) by the combination of partial demetallizing and decarbonizing of the residual oil before effecting zeolite catalytic cracking thereof is described in conjunction with a product separation process, a combined hydrocarbon gas product concentration section and the use of parallel arranged CO boilers to produce sulfur free flue gas and steam. Steam generated by the combination operation effectively reduces the energy requirement of the combustion process.
