Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

B01J 29/06

US Classification:

502 60, 502 64, 502 85

Abstract:

The present invention describes a method to increase the activity of a catalyst by first performing an ion exchange step with a potassium ion, followed by performing an ion-exchange step with an ammonium ion. Specifically, the present invention describes a method to increase the acidity of a zeolite by incorporating a potassium salt ion-exchange prior to an ammonium salt ion-exchange step. Even more specifically, the present invention is drawn to a method of increasing the activity of a zeolite by employing more than one potassium ion exchanges followed by at least one ammonium ion exchange. The present invention also describes a method to reduce the amount of sodium normally found in commercially produced zeolite by employing any of these methods. The present invention is also drawn to the catalysts produced by any of these methods.

International Classification:

B01J 21/18
B01J 27/049
B01J 23/24

US Classification:

502185, 502221, 502313

Abstract:

Bulk catalysts that include a Group VI metal, a Group VIII metal, and at least 10-60% of an organic compound based component are formed. The bulk catalysts have increased stability through the use of a stabilizer in the organic compound based component, the use of an improved gas phase sulfidation, or a combination thereof. The bulk catalysts are suitable for hydroprocessing of hydrocarbon feeds.

International Classification:

C10G 35/06
B01J 19/00
B01J 23/38

US Classification:

208134, 502 79, 502 75, 422129, 502 64

Abstract:

Process for the preparation of a catalyst suitable for use in a naphtha reforming process, the process including providing a Y zeolite with an initial SiO:AlOmolar ratio of at least 150, introducing the Y zeolite to a binder to form an intermediate composition, extruding the intermediate composition, reducing the alpha acidity of the extruded composition to provide a low acid composition, and introducing a noble metal to the low acid composition. Processes and systems of converting naphtha to a higher-octane hydrocarbon supply using catalysts, as prepared herein, are also disclosed.
