摘要： Reduced co-production of toluene and C9 and 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.

摘要： One exemplary embodiment can be an extruded C8 alkylaromatic isomerization catalyst. The extruded catalyst can include: about 2-about 20%, by weight, of an MTW zeolite; about 80-about 98%, by weight, of a binder including an alumina; about 0.01-about 2.00%, by weight, of a noble group metal calculated on an elemental basis; and about 100 ppm-less than about 1000 ppm, by weight, of at least one alkali metal calculated on an elemental basis. Generally, the weight percents of the MTW zeolite, the binder, the noble group metal, and the at least one alkali metal are based on a weight of the extruded catalyst.
