A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.

High activity and high distillate yield hydrocracking catalysts with intimate interaction between unsupported metal oxide and zeolite

This invention is drawn to a process for isomerizing a non-equilibrium mixture of xylenes and ethylbenzene which contain a substantial concentration of nonaromatics using a catalyst system which features the ability to both convert nonaromatics and to obtain an improved yield of para-xylene from the mixture relative to processes of the known art.

Aromatics isomerization using a dual-catalyst system

Aspects of the invention relate to hydrogenation catalysts, and hydrogenation processes using these catalysts, having particular characteristics, in terms of the amount and type of metal hydrogenation component (or catalytic constituent), as well as the support or substrate. The catalyst compositions, comprising both a noble metal and a lanthanide element on a substantially non-porous substrate, provide advantageous performance characteristics, including conversion, selectivity, and activity stability, as demanded in industrial hydrogenation and selective hydrogenation applications.

Method of making substantially nonporous substrate supported noble metal- and lanthanide-containing catalysts

A new family of crystalline aluminosilicate zeolites has been synthesized that has been designated UZM-43. These zeolites are similar to previously known ERS-10, SSZ-47 and RUB-35 zeolites but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out various hydrocarbon conversion processes. Catalysts made from these zeolites are useful in hydrocarbon conversion reactions.

Hydrocarbon processes using UZM-43 an EUO-NES-NON zeolite

The subject invention comprises a hydrocarbon-conversion process using a zeolitic catalyst comprising very low concentrations of non-zeolitic material and featuring a gradient in crystallinity decreasing from the outer portion to the center and an intrusion pore volume of at least 0.6 cc/gram. The catalyst is particularly effective in a xylene-isomerization process comprising ethylbenzene conversion.

Catalyst and process for hydrocarbon conversion

One exemplary embodiment may be a process for producing one or more alkylated aromatics. Generally, the process includes providing a first stream including an effective amount of benzene for alkylating benzene from a fractionation zone, providing a second stream including an effective amount of ethene for alkylating benzene from a fluid catalytic cracking zone, providing at least a portion of the first and second streams to an alkylation zone; and passing at least a portion of an effluent including ethylbenzene from the alkylation zone downstream of a para-xylene separation zone.

Substantially non-porous substrate supported noble metal-and lanthanide-containing catalysts

A process for isomerizing ethylbenzene into xylenes such as para-xylene using a zeolitic catalyst system based on low Si/AlMTW-type zeolite that preferably is substantially free of mordenite. The catalyst may be bimetallic where the two metals are platinum and tin.

Xylene and ethylbenzene isomerization process is catalyzed by the UZM-35 family of crystalline aluminosilicate zeolites represented by the empirical formula:MRAlESiOwhere M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the dimethyldipropylammonium cation and E is a framework element such as gallium. These UZM-35 zeolites are active and selective in the isomerization of xylenes and ethylbenzene.

Xylene isomerization processes, especially those processes in which ethylbenzene is also converted, are beneficially affected by adding benzene to the feed.

A process for isomerizing alkyl aromatic hydrocarbons using a catalyst comprising a zeolite and a platinum group metal component is described. The zeolite comprises a new family of zeolites designated UZM-8HS which are derived from UZM-8 zeolites by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8HS zeolites have unique x-ray diffraction patterns.
