ABSTRACT:
A catalyst composition and a process for converting a C.sub.9 + aromatic compound such as, for example, 1,2,4-trimethylbenzene to a C.sub.6 to C.sub.8 aromatic hydrocarbon such as a xylene are disclosed. The composition comprises a zeolite, a metal oxide, and optionally a selectivity modifier selected from the group consisting of silicon, sulfur, phosphorus, boron, magnesium, tin, titanium, zirconium, germanium, indium, lanthanum, cesium, oxides thereof and combinations of any two or more thereof. The process comprises contacting a fluid which comprises a C.sub.9 + aromatic compound with the catalyst composition under a condition sufficient to effect the conversion of a C.sub.9 + aromatic compound to a C.sub.6 to C.sub.8 aromatic hydrocarbon.
