Abstract:
Benzene, which is toxic and carcinogenic, is removed from a gasoline or gasoline precursor stream, such as a mixture of a reformate and a naphtha produced in a fluidized catalytic cracking unit, in a process which includes fractionating the precursor stream into a light hydrocarbon stream containing the benzene and a heavy hydrocarbon stream. The light hydrocarbon stream is then admixed with an olefinic hydrocarbon, passed through an alkylation zone and then remixed with the heavy hydrocarbon stream.
