Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
55 words
A process for hydrogenating a carbonaceous material which comprises subjecting said carbonaceous material, together with hydrogen, under hydrogenation conditions in the presence of a catalyst comprising a magnesium-deficient magnesium aluminate spinel of the following formula: Mg.sub.x Al.sub.2 O.sub.3+x, wherein x is a number ranging from about 0.10 to about 0.40, carrying nickel, titanium and molybdenum.
Claim 2
Dependent Claim
55 words
A process for hydrogenating a carbonaceous material which comprises subjecting said carbonaceous material, together with hydrogen, under hydrogenation conditions in the presence of a catalyst comprising a magnesium-deficient magnesium aluminate spinel of the following formula: Mg.sub.x Al.sub.2 O.sub.3+x, wherein x is a number ranging from about 0.10 to about 0.40, carrying nickel, titanium and molybdenum.
Claim 3
Dependent Claim
17 words
The process of claim 1 wherein x is a number ranging from about 0.2 to about 0.3.
Claim 4
Dependent Claim
11 words
The process of claim 1 wherein said carbonaceous material is coal.
Claim 5
Dependent Claim
38 words
The process of claim 1 wherein said hydrogenation is carried out at a temperature of about 260° to about 480° C. and the pressure in the range of about 100 to about 5000 pounds per square inch gauge.
Claim 6
Dependent Claim
38 words
