ABSTRACT:
Methods for the fluidized catalytic cracking of plural hydrocarbon feedstocks in a riser reactor are disclosed. The processes generally comprises contacting a relatively light hydrocarbon feedstock in a first reaction zone with a first catalyst stream comprising spent catalyst, contacting a relatively heavy hydrocarbon feedstock in a second reaction zone with a second catalyst stream comprising freshly regenerated catalyst, and introducing at least a portion of the effluent from the first reaction zone into the second reaction zone. The first reaction zone and the second reaction zone preferably comprise first and second riser reaction zones, respectively.
