Abstract:
Reduced co-production of toluene and Cand higher aromatics such as trimethylbenzene, methylethylbenzene, and diethylbenzene is achieved in processes for the isomerization of xylenes to close to equilibrium using a layered catalyst having a thin outer layer of molecular sieve and hydrogenation metal component on a core, wherein at least about 75 mass-% of the hydrogenation metal component is in the outer layer.

Abstract:
Catalysts comprising a combination of molecular sieve having a pore diameter of from about 4 to 8 angstroms and a catalytically-effective amount of molybdenum hydrogenation component in an amorphous aluminum phosphate binder provide processes for isomerizing xylene and dealkylating ethylbenzene in feed streams that exhibit stability, selectivity and low ring loss.
