ABSTRACT:
Gasoline and a heavier fraction from selective vaporization of crude or residual petroleum stocks are separately supplied to a riser reactor of the FCC type. The crude or resid is contacted at low cracking severity with hot inert solids in a riser. The vaporized product is fractionated to provide a gasoline injected to the bottom of an FCC riser and a bottoms fraction introduced at a higher point in the FCC riser.
