摘要: A catalyst for the disproportionation/transalkylation of various hydrocarbons consists of a carrier and a metal component supported on the carrier. The carrier comprises 10 to 80 wt % of mordenite and/or beta type zeolite with a mole ratio of silica/alumina ranging from 10 to 200; 0 to 70 wt % of ZSM-5 type zeolite with a mole ratio of silica/alumina ranging from 30 to 500; and 5 to 90 wt % of at least one inorganic binder selected from the group consisting of gamma-alumina, silica, silica alumina, bentonite, kaolin, clinoptilolite, and montmorillonite. The metal component comprises platinum and either tin or lead. The catalyst enables mixed xylenes to be produced at remarkably high yields from benzene, toluene and C9 or higher aromatic compounds through disproportionation/transalkylation with a great reduction in aromatic loss. In addition, the catalyst can maintain its catalytic activity for a long period of time without deactivation.
