Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
58 words
In a process wherein a feed material comprising a mixture of a shale oil material and a petroleum material are heated in the substantial absence of oxygen to produce coke and a liquid product, the improvement wherein said feed material contains a hydrogen catalyst selected from the group consisting of hydrogen transfer catalysts, hydrogenation catalysts, and hydrocracking catalysts.
Claim 2
Dependent Claim
58 words
In a process wherein a feed material comprising a mixture of a shale oil material and a petroleum material are heated in the substantial absence of oxygen to produce coke and a liquid product, the improvement wherein said feed material contains a hydrogen catalyst selected from the group consisting of hydrogen transfer catalysts, hydrogenation catalysts, and hydrocracking catalysts.
Claim 3
Dependent Claim
20 words
The process of claim 1 wherein said feed material contains from greater than 0 to 10 weight % hydrogen catalyst.
Claim 4
Dependent Claim
18 words
The process of claim 2 wherein said feed material contains from 0.01 to 5 weight percent hydrogen catalyst.
Claim 5
Dependent Claim
14 words
The process of claim 1 wherein said hydrogen catalyst is a hydrogen transfer catalyst.
Claim 6
Dependent Claim
19 words
The process of claim 4 wherein said hydrogen transfer catalyst is selected from the group consisting of iron pyrites.
Claim 7
Dependent Claim
13 words
The process of claim 1 wherein said hydrogen catalyst is a hydrogenation catalyst.
Claim 8
Dependent Claim
21 words
The process of claim 6 wherein said hydrogenation catalyst is selected from the group consisting of metallic nickel, platinum and palladium.
Claim 9
Dependent Claim
13 words
The process of claim 1 wherein said hydrogen catalyst is a hydrocracking catalyst.
Claim 10
Dependent Claim
21 words
The process of claim 8 wherein said hydrocracking catalyst is selected from the group consisting of NiMo, CoMo, NiW and CoW.
Claim 11
Dependent Claim
13 words
The process of claim 9 wherein said hydrocracking catalyst includes an alumina support.
Claim 12
Dependent Claim
17 words
The process of claim 1 wherein said feed material containing said hydrogen catalyst is mixed during coking.
Claim 13
Dependent Claim
37 words
The process of claim 1 further comprising withdrawing coke from the reaction zone wherein coking has occurred, mixing the hydrogen catalyst contained in said coke with additional feed material and subjecting said additional feed material to coking.
Claim 14
Dependent Claim
38 words
The process of claim 12 wherein coke passing out of said reaction zone is combusted so that said hydrogen catalyst is recovered in the form of an ash and said ash is mixed with said additional feed material.
Claim 15
Dependent Claim
19 words
The process of claim 12 wherein coke removed from said reaction zone is mixed with said additional feed material.
Claim 16
Dependent Claim
63 words
In a process wherein a feed material comprising a mixture of a shale oil material and a petroleum material consisting of petroleum derived residua are heated in the substantial absence of oxygen to produce coke and a liquid product, the improvement wherein said feed material contains a hydrogen catalyst selected from the group consisting of hydrogen transfer catalysts, hydrogenation catalysts, and hydrocracking catalysts.
Claim 17
Dependent Claim
63 words
In a process wherein a feed material comprising a mixture of a shale oil material and a petroleum material consisting of petroleum derived residua are heated in the substantial absence of oxygen to produce coke and a liquid product, the improvement wherein said feed material contains a hydrogen catalyst selected from the group consisting of hydrogen transfer catalysts, hydrogenation catalysts, and hydrocracking catalysts.
