IMPROVED CATALYTIC REFORMING METHOD FOR PRODUCTION OF BENZENE AND TOLUENE ABSTRACT OF THE DISCLOSURE An improved hydrocarbon reforming process involves contacting hydrocarbon feed comprising benzene and toluene precursors in at least two reaction zones which include a platinum group metal-containing catalyst. Improved yields of benzene are obtained provided that the inlet temperature of each succeeding reaction zone is increased relative to the inlet temperature of the immediately preceding reaction zone. Also, improved benzene yields are obtained by providing a limited water concentration in at least one of the reaction zones. Further, improved toluene yields are obtained by operating at least one of the reaction zones at substantially anhydrous conditions.
