ABSTRACT:
A catalytic process is provided for the selective production of para-xylene by contacting, under conversion conditions, a charge stock containing, as a major reactant, at least one hydrocarbon selected from the group consisting of toluene, a C.sub.3 -C.sub.10 olefin, a C.sub.5 -C.sub.10 naphthene, a C.sub.3 -C.sub.10 paraffin, and mixtures of the foregoing with a catalyst comprising a composite of a crystalline aluminosilicate zeolite and antimony oxide, said zeolite having a silica to alumina ratio of at least about 12 and a constraint index, as hereinafter defined, within the approximate range of 1 to 12.
