    摘要: 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.The catalytic reaction also causes the conversion of a small amount of light olefins in the fuel gas to coke by-product and the deposition of coke on the catalyst. The deposited coke causes the partial deactivation of the catalyst. A portion of the partially deactivated catalyst is continuously or intermittently withdrawn from the riser reactor and regenerated in a catalyst regenerator by contacting the catalyst with hydrogen containing regeneration gas or by contacting the catalyst with an oxygen containing regeneration gas to remove substantially all of the coke from the catalyst. The regenerated catalyst is introduced in the riser reactor and contacted with fresh feed.
