Abstract

The benzene content of light reformate is reduced by selectively alkylating the toluene contained therein with olefins by contacting the light reformate with the olefins in a catalyst bed. The catalyst structure in the catalyst bed acts as both a catalyst for the alkylation reaction and as distillation structure thus immediately separating the reaction product from the reaction zone to prevent reverse reactions and increase the overall reaction rate. The alkylated toluene is then used to transalkylate benzene to reduce the amount of benzene in the gasoline.
