Abstract
A process is disclosed for increasing the octane number of an FCC unit gasoline pool by upgrading selected gasoline boiling-range streams. FCC gasoline is mixed with the feed to a light olefin upgrading reactor. Upgraded gasoline is then fractionated in an existing FCC gas plant.
Claims11
An integrated catalytic cracking and gasoline upgrading process comprising the steps of:
- (a) withdrawing a product stream from the riser reactor of a catalytic cracking process unit;
- (b) charging said product stream to a primary fractionation zone;
- (c) withdrawing an intermediate gasoline stream from said primary fractionation zone, said intermediate gasoline stream comprising olefinic gasoline having an ASTM D86 boiling range from about 90.degree. to about 170.degree. C.;
- (d) contacting a first portion of said intermediate gasoline stream and a C.sub.2 -C.sub.5 olefinic stream with a catalyst under conversion conditions to form an upgraded gasoline stream;
- and
- (e) charging a second portion of said intermediate gasoline stream together with said upgraded gasoline stream to a gasoline product storage facility.
