Abstract (en)
[origin: WO9955801A1] The invention is directed to a Fluid Catalytic Cracking process conducted in a fluid catalytic cracking unit (FCCU) comprising one or more risers, each of said risers having a plurality of injection nozzles therein and at least one reaction zone therein comprising the steps of spatially nonuniformly injecting a plurality of feeds wherein said plurality of feeds comprises at least one feed ( alpha ) and at least another feed ( beta ), wherein said feeds ( alpha ) and ( beta ): (a) differ in Conradson Carbon Residue by at least about 2 wt.% points or (b) differ in hydrogen content by at least about 0.2 wt.%; or (c) differ in API gravities by at least about 2 points; or (d) differ in nitrogen content by at least about 50 ppm; or (e) differ in carbon-to-hydrogen ratio by at least about 0.3; or (f) differ in mean boiling point by at least about 200 DEG F; and wherein said spatially nonuniform injection is accomplished by (i) simultaneously injecting into a single reaction zone of a single riser said feed ( alpha ) from at least one injection nozzle of said riser and said feed ( beta ) from the remaining nozzles of said riser; (ii) simultaneously injecting said feed ( alpha ) into at least one of said reaction zones of said riser of said FCCU and said feed ( beta ) into another of said reaction zones of said riser of said FCCU; or (iii) simultaneously injecting said feed ( alpha ) into at least one riser of said FCCU and said feed ( beta ) into a second riser of said FCCU. Wherein when said spatially nonuniform injection is accomplished by (iii), said feeds are substantially non-paraffinic feeds.
