US Patent:

46594523, Apr 21, 1987
Filed:

May 23, 1986
Appl. No.:

6/866424
Inventors:

Jerald A. Howell - Bartlesville OK
Assignee:

Phillips Petroleum - Bartlesville OK
International Classification:

C10G 6510
C10G 6512
US Classification:

208 89
Abstract:

A two-stage hydrotreating process comprises the steps of (1) contacting a liquid hydrocarbon-containing feed stream, which contains nickel, vanadium and Ramsbottom carbon residue, with hydrogen and a solid inorganic refractory material (preferably alumina) for at least partial removal of Ni and V, and then (2) hydrovisbreaking the intermediate product stream from step (1). Preferably, step (2) is carried out in the presence of at least one decomposable compound of a metal, preferably a molybdenum dithiophosphate.

C10G 4704
US Classification:

208112
Abstract:

At least one decomposable molybdenum compound selected from the group consisting of molybdenum dithiophosphates and molybdenum dithiocarbamates is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable molybdenum compound is then contacted in a hydrovisbreaking process with hydrogen under suitable hydrovisbreaking conditions.

US Classification:

208108
Abstract:

At least one decomposable molybdenum additive selected from the group consisting of a mixture of a molybdenum dithiophosphate and a molybdenum carboxylate and a mixture of a molybdenum dithiocarbamate and a molybdenum carboxylate is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable molybdenum additive is then contacted in a hydrovisbreaking process with hydrogen under suitable hydrovisbreaking conditions.

Filed:

Jan 28, 1985
Appl. No.:

6/695786
Inventors:

Simon G. Kukes - Bartlesville OK

Jerald A. Howell - Bartlesville OK
Assignee:

Phillips Petroleum Company - Bartlesville OK
International Classification:

C10G 4506
US Classification:

208251H
Abstract:

At least one decomposable compound selected from the group consisting of compounds of the metals of Group IIB and Group IIIB of the Periodic Table is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable compound is then contacted in a hydrofining process with a catalyst composition comprising a support selected from the group consisting of alumina, silica and silica-alumina and a promoter comprising at least one metal selected from Group VIB, Group VIIB and Group VIII of the Periodic Table. The introduction of the decomposable compound may be commenced when the catalyst is new, partially deactivated or spent with a beneficial result occurring in each case.
