53088140, May 3, 1994

Filed:

May 8, 1992

Appl. No.:

7/880492

Inventors:

Simon G. Kukes - Naperville IL
Frederick T. Clark - Wheaton IL
P. Donald Hopkins - St. Charles IL

Assignee:

Amoco Corporation - Chicago IL

International Classification:

B01J 2910

US Classification:

502 66

Abstract:

A process and catalyst are provided for hydrogenation of a hydrocarbon feedstock consisting essentially of material boiling between about 150. degree. F. and about 700. degree. F. which comprises reacting the feedstock with hydrogen at hydrogenation conditions in the presence of a catalyst comprising hydrogenation metals and a support comprising zeolite Y. The hydrogenation metals comprise from about 0. 1 percent to about 2. 0 percent by weight each of palladium and platinum calculated as a percentage of the catalyst. The zeolite Y further comprises sodium in an amount ranging from about 1. 5 to about 8. 0 percent of the zeolite Y by weight. The process of the present invention provides substantially improved dearomatization performance, increased desulfurization and denitrogenation, increased distillate product cetane number, and increased distillate volume expansion.

US Classification:

208143

Abstract:

A process and catalyst are provided for the hydrogenation of a hydrocarbon feedstock consisting essentially of hydrocarbon boiling between about 150. degree. F. and 700. degree. F. at atmospheric pressure. The process comprises reacting the feedstock with hydrogen at hydrogenation conditions in the presence of a catalyst comprising hydrogenation metals and a support comprising beta zeolite. The hydrogenation metals comprise from about 0. 1 percent by weight to about 2. 0 percent by weight each of palladium and platinum measured as a percentage of the catalyst. The beta zeolite comprises from about 1 ppm by weight to about 3. 0 percent by weight sodium calculated as a percentage of said beta zeolite.

Appl. No.:

7/502297

Inventors:

Frederick T. Clark - Wheaton IL

David Lyzinski - Wheaton IL
Lawrence B. Peck - Houston TX

Assignee:

Amoco Corporation - Chicago IL

International Classification:

C10G 4504

US Classification:

208216PP

Abstract:

Disclosed is an improved process for the hydrodemetallization, hydrodesulfurization, hydrodenitrogenation, and hydroconversion of a hydrocarbon feedstock containing asphaltenes, metals and Shell hot filtration solids precursors. The process utilizes a catalyst mixture wherein one component of the mixture is a relatively small pore catalyst and another component is a catalyst that possesses a relatively large amount of macropore volume.

Assignee:

Amoco Corporation - Chicago IL

International Classification:

C10G 6704
C10G 6910

US Classification:

208 87

Abstract:

A method for reducing the pour point of a hydrocarbon feedstock that contains aromatic compounds, sulfur-containing compounds and nitrogen-containing compounds is provided. The method involves solvent extraction and utilizes a catalytic hydrodewaxing zone with a first section having a shape-selective molecular sieve-containing catalyst composition which is substantially free of Group VIII metals and a second section having a Group VIII metal-containing hydrogenation catalyst composition with a porous support material substantially free of acidic crystalline molecular sieve material.
