International Classification:

C07C 5/27

US Classification:

585481, 585482

Abstract:

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.

Abstract:

The apparatus converts FCC olefins to heavier compounds. The heavier compounds are more easily separated from the unconverted paraffins. The heavier compounds can be recycled to an FCC unit or delivered to a separate FCC unit. Suitable conversion zones are oligomerization and aromatic alkylation zones.

Abstract:

A process for removing a refractory nitrogen compound from a hydroprocessed vacuum gas oil feed includes contacting the hydroprocessed vacuum gas oil feed comprising the nitrogen compound with a VGO-immiscible phosphonium ionic liquid to produce a hydroprocessed vacuum gas oil and VGO-immiscible phosphonium ionic liquid mixture, and separating the mixture to produce a hydroprocessed vacuum gas oil effluent having a reduced refractory nitrogen compound content relative to the vacuum gas oil feed.
