Abstract
A process is described for reducing the level of benzene in a refinery gasoline feed containing benzene and at least one Colefin, in which the refinery gasoline feed is contacted with a first alkylation catalyst under conditions effective to react at least part of the Colefin and benzene in the refinery gasoline feed and produce a first alkylation effluent. The first alkylation effluent is separated into at least (i) a first fraction rich in benzene, (ii) a second fraction rich in Cto Chydrocarbons and (iii) a third fraction rich in Chydrocarbons. At least part of the first fraction is contacted with an alkylating agent comprising one or more Cto Colefins in the presence of a second alkylation catalyst under conditions effective to produce a second alkylation effluent which has reduced benzene content as compared with the first fraction.
