ABSTRACT:
The benzene concentration in the gasoline pool of a petroleum refinery is decreased by alkylation of the benzene in a catalytic dewaxing reactor using the olefinic by-products from the dewaxing reaction as alkylating agents. The catalytic dewaxing is preferably carried out in the presence of an intermediate pore size zeolite such as ZSM-5 using a distillate or lube boiling range dewaxing feed. The benzene rich feed preferably contains less than about 2% C.sub.7+ aromatics in order to reduce alkylation of non-objectionable species in the reformate.
