Patent ID: 6867340

Claim:
A process for producing mixed xylenes from aromatic hydrocarbons, said process comprising: (A) providing an aromatic hydrocarbon feedstock comprising: (1) toluene and (2) C9 or higher aromatic hydrocarbons; (B) converting said aromatic hydrocarbons in said feedstock into mixed xylenes by contacting said feedstock with hydrogen in the presence of a catalyst, said catalyst comprising: (1) a carrier comprising: (a) 10 to 80 wt % of at least one of (i) mordenite and (ii) beta type zeolite, said mordenite and said beta type zeolite having a mole ratio of silica to alumina of from 10 to 200; (b) from greater than 0 up to 70 wt % of ZSM-5 type zeolite having a mole ratio of silica to alumina of from 30 to 500; and (c) 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; and (2) a metal component, supported on said carrier, said metal component comprising: (a) platinum, and (b) either tin or lead; and (C) recovering said mixed xylenes.
