ABSTRACT:
A process and apparatus for short contact time fluidized catalytic cracking of heavy oil feed using a reactor with an upflow cat:oil vaporizer and a downflow reactor. Catalyst slip permits efficient mixing and limited conversion in the upflow section, while cracking is completed in the downflow reactor with minimal segregation of catalyst. FCC catalyst with more than 25 wt % Y zeolite content is preferred, and total vapor residence time should be less than 5 seconds.
