Abstract
A process for the reduction of benzene in a gasoline stream, the process including: feeding a gasoline fraction including benzene and Chydrocarbons and at least one of an alcohol and an ether to a catalytic distillation column comprising at least one reaction zone containing an alkylation catalyst, wherein the at least one reaction zone is above a gasoline fraction feed location; concurrently in the catalytic distillation column: separating the Chydrocarbons from Chydrocarbons, wherein the Chydrocarbons and benzene distill upward into the at least one reaction zone; contacting benzene and the at least one of an alcohol and an ether in the at least one reaction zone in the presence of the alkylation catalyst to convert at least a portion of the benzene and alcohol/ether to an alkylate; recovering an overheads fraction including Chydrocarbons, any unreacted alcohol and ether, and water; and recovering a bottoms fraction including Chydrocarbons and the alkylate.
