Abstract
Abstract A process for hydrotreating a whole shale oil or a shale oil fraction containing at least about 0.1 wt. % nitrogen comprises a catalyst comprising a chromium component, a molybdenum component, a phosphorus component, and at least one of a cobalt component and a nickel component, deposed on a support comprising at least one porous refractory inorganic oxide. Hydrotreatment comprises contacting a hydrocarbon stream, e.g., a whole shale oil. with hydrogen in the presence of the invented catalyst under hydrotreatment conditions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
72 words
A process for hydrotreatment of a hydrocarbon feed wherein the hydrocarbon feed comprises a whole shale oil or a shale oil fraction and contains at least about 0.1 wt.% nitrogen, comprising contacting the hydrocarbon feed with hydrogen under hydrotreatment conditions in the presence of a catalyst comprising a phosphorus component, a chromium component, a molybdenum component and a cobalt component, deposed on a support comprising at least one porous refractory inorganic oxide.
Claim 2
Dependent Claim
72 words
A process for hydrotreatment of a hydrocarbon feed wherein the hydrocarbon feed comprises a whole shale oil or a shale oil fraction and contains at least about 0.1 wt.% nitrogen, comprising contacting the hydrocarbon feed with hydrogen under hydrotreatment conditions in the presence of a catalyst comprising a phosphorus component, a chromium component, a molybdenum component and a cobalt component, deposed on a support comprising at least one porous refractory inorganic oxide.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein the support is an alumina or silica-alumina containing up to about 50 weight percent silica.
Claim 4
Dependent Claim
85 words
The process of claim 1 wherein the catalyst comprises from about 1 to about 15 weight percent phosphorus, calculated as P 2 O 5 , from about 1 to about 30 weight percent chromium, calculated as Cr 2 O 3 , from about 1 to about 20 weight percent molybdenum, calculated as MoO 3 and from about 0.1 to about 7 weight percent of cobalt, calculated as CoO, and deposed on a support comprising alumina or a silica-alumina containing up to about 50 wt.% silica.
Claim 5
Dependent Claim
76 words
The process of claim 1 wherein the hydrogen partial pressure is from about 1,000 psi to about 2,000 psi (6.9-13.8 MPa), the average reaction temperature of from about 700° F. to about 820° F. (317° to 438° C.), an LHSV of from about 0.1-8 volumes of hydrocarbon per hour per volume of catalyst, and a hydrogen recycle rate or addition rate of from about 1,000 SCFB to about 10,000 SCFB (178-1780 m 3 /m 3 ).
