    摘要: The use of a layered catalyst composition to selectively hydrogenate C5-C11 diolefins in a hydrocarbon mixture to one or more respective C5-C11 monoolefins is disclosed. The layered catalyst comprises an inner core having a first inorganic oxide and an outer layer bonded to the inner core. The outer layer has a non-refractory second inorganic oxide with at least one Group 1-2 metal and at least one Group 8-10 metal dispersed thereon.

    摘要: An improved process combination is disclosed for the selective disproportionation of toluene. The combination comprises selective hydrogenation of a toluene feedstock followed by disproportionation using a zeolitic catalyst which is oil-dropped in an aluminum phosphate binder to achieve a high yield of paraxylene. Optionally, the catalyst is selectively precoked prior to toluene disproportionation. The catalyst and process provide improved selectivity for the production of paraxylene.
