US Patent:

40438988, Aug 23, 1977

Filed:

Aug 25, 1975

Appl. No.:

5/607728

Inventors:

William H. Kegler - Ponca City OK

Assignee:

Continental Oil Company - Ponca City OK

International Classification:

C10G 914

US Classification:

208 50

Abstract:

Characteristics of the feedstock for a delayed coking operation are determined prior to carrying out the coking operation, and the feedstock is adjusted by blending, thermal cracking, or other processing to provide certain predetermined characteristics to the feedstock prior to conducting the coking operation. Feedstocks having desired predetermined characteristics produce a premium grade coke having very low coefficient of thermal expansion.

Appl. No.:

6/024345

Inventors:

William H. Kegler - Ponca City OK
James R. McConaghy - Ponca City OK

Assignee:

Conoco, Inc. - Ponca City OK

International Classification:

C10G 914
C10G 5504

US Classification:

208 89

Abstract:

A petroleum refinery residual oil derived from a naphthenic crude oil is catalytically demetalized, catalytically desulfurized and then fed to a delayed coker to produce premium delayed coke.

Appl. No.:

5/500985

Inventors:

William H. Kegler - Ponca City OK
Marvin E. Huyser - Houston TX

Assignee:

Continental Oil Company - Ponca City OK

International Classification:

C10G 914

US Classification:

208 50

Abstract:

Isotropic petroleum coke is produced by air blowing a petroleum residuum to produce a delayed coking feedstock having a particular softening point and then coking said air-blown residuum with or without diluent under delayed coking conditions.

Appl. No.:

5/925250

International Classification:

C10G 914

US Classification:

208 50

Abstract:

A delayed coking process in which the overhead vapors from a delayed coking drum are separated into light hydrocarbon products and a gas oil, and in which the gas oil is hydrotreated after being separated from the light hydrocarbon products. The hydrotreated gas oil is then combined with coker feedstock and fed to the coking drum. The process produces a coke capable of producing a graphitized product having a lower longitudinal coefficient of thermal expansion than that of the coke product produced from the same feedstock by the same process but without the hydrotreating step.
