International Classification:

C10G045/04

US Classification:

502/313000, 208/217000, 208/21600R, 208/213000

Abstract:

A high-activity hydrotreating catalyst, having a low density, suitable for deep removal of sulfur, nitrogen, micro-carbon residue and organometallic contaminants from hydrocarbon feedstocks is disclosed. Further disclosed is a method of preparation of this catalyst, which may contain 0.3-10 wt % of a Group IVB metal promoter, 5-25 wt % of a Group VIB metal component, and 1-8 wt % of a Group VIII metal, along with a method of hydrotreating employing this catalyst.

Filed:

Sep 28, 1984

Appl. No.:

6/655987

Inventors:

Kirk R. Gibson - El Cerrito CA

Assignee:

Chevron Research Company - San Francisco CA

International Classification:

C10G 4508
C10G 6504

US Classification:

208210

Abstract:

A process for hydrotreating hydrocarbon feedstocks using shaped catalysts is disclosed. When the catalyst is used for diffusion limited reactions, and particularly when it is used for demetalation, shaped catalysts give longer catalyst lifetimes. Preferred shaped include oval and elliptical shapes, with and without bumps.

International Classification:

B01J 2106
B01J 2385
B01J 2388

US Classification:

502309

Abstract:

A method for making a hydrotreating catalyst wherein the catalyst is prepared by mixing a peptized hydrated supporting oxide with a hydrated Group IVB metal oxide gel promoter. The Group VIII metals are mixed in with the Group IVB metal oxide gel promoter. A solution containing a soluble Group VIB metal and a basic compound is added. The catalyst is used for hydrodenitrogenation and Ramsbottom Carbon Residue reduction of a hydrocarbon feedstock.

Filed:

Jun 12, 1978

Appl. No.:

5/915022

Inventors:

Robert L. Jacobson - Hercules CA
Kirk R. Gibson - El Cerrito CA

Assignee:

Chevron Research Company - San Francisco CA

International Classification:

C10G 2916
C10G 2906
C10G 2904

US Classification:

208243

Abstract:

Thiol impurities are absorbed and removed from hydrocarbon oils by contacting the oil in the absence of molecular oxygen with a scavenger at a temperature in the range of about 120. degree. to 400. degree. C. The scavenger is a composite having a copper component and an inorganic porous carrier component and having a surface area in the range 20 to 1000 square meters per gram. The contacting must be discontinued when the thiol impurity content of the effluent product exceeds about 0. 3 ppm.
