Abstract
Abstract Carbonaceous feeds such as hydrocarbonaceous oils and coal are hydroconverted in the presence of a combination of a hydrogen halide and a metal-containing catalyst produced in situ in the feed. The hydrogen halide is present in an amount to provide from about 0.1 to 20 moles of hydrogen halide per atom of the metal constituent of the catalyst to increase the activity of the catalyst.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
137 words
In a process for the hydroconversion of a carbonaceous feed which comprises: (a) forming a mixture of said carbonaceous feed and a thermally decomposable metal compound wherein said metal compound comprises at least one metal constituent selected from the group consisting of Group II, III, IVB, VB, VIB, VIIB, VIII and mixtures thereof of the Periodic Table of Elements; (b) reacting the resulting mixture with a hydrogen-containing gas at hydroconversion conditions, in a hydroconversion zone, said metal compound being converted to a metal-containing catalyst within said mixture at said conditions, and (c) recovering a normally liquid hydrocarbon product, the improvement which comprises said reaction being conducted in the presence of a hydrogen halide in an amount such as to provide a ratio from about 0.1 to about 20 gram-moles hydrogen halide per gram-atom of said metal constituent.
Claim 2
Dependent Claim
