Abstract:
1. A process for controlling the 2-phenyl content of an alkylbenzene product stream comprising: passing a benzene stream into a first reactor in a plurality of reactor beds in a series arrangement, wherein the plurality of reactors comprises two or more reactors and each reactor bed is operated at benzene alkylation reaction conditions, wherein a single catalyst type is used for all of the reactor beds, wherein the catalyst comprises a first zeolite comprising UZM-8 and a second zeolite comprising a rare earth substituted X or Y zeolite intermingled into single catalyst particles; splitting a feed olefin stream to at least two olefin streams, creating at least a first olefin stream and a second olefin stream, where the sum of the olefin streams comprises the total olefin flow, wherein the olefin comprises olefins having from 9 to 20 carbon atoms; passing the first olefin stream to the first reactor bed, thereby generating a first reactor bed effluent stream; passing the first reactor bed effluent stream and the second olefin stream to a second reactor bed thereby generating a second reactor bed effluent stream, comprising an alkylbenzene product; and controlling the ratio of second olefin stream to the total olefin flow to generate a specified 2-phenyl content of the alkylbenzene product.
