Abstract
Abstract A heavy hydrocarbonaceous oil containing a Group IB, IVB, VB, VIB, VIIB or VIII transition metal compound is upgraded by treatment with hydrogen or a hydrogen donor compound in the presence of an aluminum alkyl compound, for example, triethyl aluminum. The transition metal compound may be naturally occurring in the oil or added to the oil. A preferred transition metal compound is vanadyl phthalocyanine.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
58 words
A process for hydrorefining a heavy hydrocarbonaceous oil containing metal compounds naturally occurring in said oil, which comprises, contacting said heavy oil, in a hydrorefining zone, with hydrogen and an aluminum alkyl compound, at hydrorefining conditions, including a temperature ranging from about 500° to about 1500° F. and a pressure ranging from about 500 to about 3000 psig.
Claim 2
Dependent Claim
58 words
A process for hydrorefining a heavy hydrocarbonaceous oil containing metal compounds naturally occurring in said oil, which comprises, contacting said heavy oil, in a hydrorefining zone, with hydrogen and an aluminum alkyl compound, at hydrorefining conditions, including a temperature ranging from about 500° to about 1500° F. and a pressure ranging from about 500 to about 3000 psig.
