Abstract

A process wherein a residuum feedstock is upgraded in a short vapor contact time thermal process unit comprised of a horizontal moving bed of fluidized hot particles, then fed to a fluid catalytic cracking process unit. Hot flue gases from the fluid catalytic cracking unit is used to circulate solid particles and to provide process heat to the thermal process unit.
