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°to about 170°C.; (d) contacting a first portion of said intermediate gasoline stream and a C2-C5 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.
