摘要:
Xylene and ethylbenzene isomerization process is catalyzed by the UZM-35 family of crystalline aluminosilicate zeolites represented by the empirical formula: Mmn+Rr+Al(1-x)ExSiyOz where 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.

A new family of crystalline aluminosilicate zeolites has been synthesized. These zeolites are represented by the empirical formula. Mmn+Rr+Al(1-x)ExSiyOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the propyltrimethylammonium cation and E is a framework element such as gallium. These zeolites are similar to MWW but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out alkylation processes.

摘要:
A process for the use in the oligomerization of olefins is presented. The process produces a gasoline boiling range product having a high research octane number and almost no aromatics content. The process utilizes a solid catalyst comprising a zeolite that is treated with a phosphorous containing reagent to generate a catalyst having phosphorous content between 0.5 and 15 wt %.

A catalyst, and the process for producing the catalyst, for use in the oligomerization of olefins is presented. The catalyst comprises a zeolite that is treated with a phosphorous containing reagent to generate a treated catalyst having phosphorous content between 0.5 and 15 wt %, and having a micropore volume of less than 50% of the untreated catalyst.

摘要:
One exemplary embodiment can be a process for producing a gasoline. The process can include contacting a feed having a naphtha and recycling at least a portion of the reaction zone effluent to the one or more reforming reaction zones. Generally, the reformate includes no more than about 15%, by volume, benzene, with a UZM-8 catalyst in one or more reforming reaction zones to produce a reaction zone effluent.
