Abstract:
A process is presented for the management and control of the 2-phenyl content in a benzene alkylation process. The process includes the use of multiple reactor beds, with benzene flowing through the reactor beds in a sequential manner. The olefin stream is split to two or more portions, and a separate portion is passed to the first reactor bed and second reactor bed. Control of the ratio of the olefin flow splits controls the 2-phenyl content.
