US Classification:

585467, 585481, 585475, 585722

Abstract:

Hydrocarbon conversion processes using a new family of zeolites identified as UZM-8 and UZM-8HS are described. The UZM-8 and UZM-8HS are related in that the UZM-8HS are derived from the UZM-8 zeolite by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8 and -8HS have unique x-ray diffraction patterns. These zeolites can be used in alkylation of aromatics, transalkylation of aromatics, isomerization of aromatics and alkylation of isoparaffins.

US Classification:

585481, 585482

Abstract:

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.

International Classification:

C07C 6/12

US Classification:

585475

Abstract:

One exemplary embodiment can be a method for processing polyisopropylbenzene for producing cumene. The method can include passing a transalkylation feed stream to a transalkylation zone, and passing a reaction product to a separation zone. Typically, the separation zone produces a stream including di-isopropylbenzene, tri-isopropylbenzene, and one or more heavy compounds. Moreover, the stream may include at least about 0. 7%, by weight, of the one or more heavy compounds based on the weight of the di-isopropylbenzene, tri-isopropylbenzene, and the one or more heavy compounds in the stream, and at least a portion of the stream is recycled to the transalkylation zone.

Abstract:

A aromatic alkylation catalyst, processes for producing the catalyst, and aromatic alkylation processes employing the catalysts are disclosed. The catalyst comprises a UZM-8 zeolite and nitrogen, and the catalyst has a nitrogen to zeolite aluminum molar ratio of at least about 0. 015. In an exemplary alkylation process, the catalyst provides improved product yield.

Abstract:

Catalysts for converting polyalkylaiomatics to monoalkylaromatics, particularly cumene and ethyl benzene are disclosed which comprise modified Y-85 or LZ-210 zeolites. For cumene and ethylbenzene production, a disclosed catalyst, made of 80 wt % zeolite and 20 wt % alumina binder on a volatile-flee basis, has one or more of the following physical characteristics: (1) an absolute intensity of the modified Y zeolite as measured by X-ray diffraction (XRD) of preferably at least 50 and (2) a framework aluminum of the modified Y zeolite of preferably at least 50% of the aluminum of the modified Y zeolite.
