Abstract

The present invention relates to a process for producing gasoline having a reduced alkene content and a reduced organosulfur content. The process of the invention comprises contacting gasoline obtainable by a fluid catalytic cracking process, which gasoline comprises ≥1 alkene and ≥1 organosulfur compd., with an extn. solvent suitable for extg. alkenes and organosulfur compds., which extn. solvent comprises a polar org. solvent, and thereby forming (i) a 1st phase comprising said extn. solvent, at least 1 extd. alkene, and ≥1 extd. organosulfur compd., and (ii) a 2nd phase comprising gasoline having a reduced alkene content and a reduced organosulfur content compared to said gasoline obtainable by a fluid catalytic cracking process. A process for producing ≥1 further org. compds. is also provided, which process comprises: (a) providing a recovered 1st phase from the above process, and (b) performing a reaction on at least part of the recovered 1st phase to produce ≥1 further org. compds. A compn., an app. and the use of an extn. solvent are also provided.
