Petroleum refinery process and apparatus for the production of alkyl aromatic hydrocarbons from fuel gas and catalytic reformate
This paper describes a process for the production of gasoline. It comprises: contacting a feed stream comprising C{sub 4}{sup {minus}} olefin hydrocarbons with a feed stream comprising C{sub 6} to C{sub 8} aromatic hydrocarbons at an aromatic to olefin weight ratio of 5:1 to 20:1 over a fluidized zeolite catalyst at a temperature of 350{degrees} to 900{degrees}F a pressure of 20 to 650 psig in a riser reactor having multiple olefin feed injection points to alkylate the C{sub 6}-C{sub 8} aromatics with the olefins to form C{sub 7} to C{sub 11} alkyl aromatic hydrocarbon gasoline products, wherein the multiple olefin feed injection points are spaced along the height of the riser reactor and the aforethe aromatic to olefin weight ratio is maintained throughout the riser reactor and withdrawing a portion of the catalyst from the riser for regeneration of the catalyst the withdrawn catalyst containing only a minor amount of deposited coke.
