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 a regeneration process for a C8 alkylaromatic isomerization catalyst. The process can include:contacting the C8 alkylaromatic isomerization catalyst with a first gas stream comprising an oxidizing gas at a first stage for a first time period and a first temperature effective to remove at least a portion of a carbonaceous material from the C8 alkylaromatic isomerization catalyst; andcontacting the C8 alkylaromatic isomerization catalyst with a second gas stream comprising the oxidizing gas at a second stage for a second time period and a second temperature effective to remove another portion of the carbonaceous material from the C8 alkylaromatic isomerization catalyst.

The catalyst can include: about 1-about 90%, by weight, of a zeolite including an MTW zeolite; about 10-about 99%, by weight, of a binder including a gamma-alumina, the gamma-alumina being derived from a Boehmite alumina; about 0.1-about 2%, by weight, of a noble metal, calculated on an elemental basis; and at least one alkali metal wherein a total alkali metal content of the catalyst is at least about 100 ppm, by weight, calculated on an elemental basis. Generally, the catalyst has a pore volume distribution and at least about 70% of a pore volume of the catalyst is defined by pores having a diameter greater than about 100 Å.
