ABSTRACT:
A petroleum refinery process for the production of alkyl aromatic hydrocarbons from a C.sub.4.sup.- fuel gas containing light olefins including ethene and propene and catalytic reformate containing C.sub.6 to C.sub.8 aromatics. The C.sub.4.sup.- fuel gas is contacted with the catalytic reformate at a weight ratio of aromatics to olefins of 10:1 to 15:1 over a zeolite catalyst under process conditions to alkylate the C.sub.6 to C.sub.8 aromatics, particularly benzene, in the reformate with ethene and propene in the C.sub.4.sup.- fuel gas to form alkyl aromatic hydrocarbons. The reaction is carried out in a riser reactor having multiple olefin feed injection points in the riser section of the reactor.
