Title:
芳香族炭化水素の不均化/トランスアルキル化のための触媒及びその製造方法
Document Type and Number:
Japanese Patent JP4351393
Kind Code:
B2
Abstract:
Disclosed are a catalyst for the disproportionation/transalkylation of various hydrocarbons and methods for preparing the same. The catalyst 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; up 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 wherein said tin or lead is present in an amount of at least 3 times more than that of platinum. 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.
