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.
Claims12
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.degree. to about 1500.degree. F. and a pressure ranging from about 500 to about 3000 psig.
A process for hydrorefining a heavy hydrocarbonaceous oil containing at least 1 weight percent sulfur and naturally occurring metal compounds, said metal compounds, said metal compounds comprising at least one metal selected from the group consisting of Groups IB, IVB, VB, VIB, VIIB, VIII and mixtures thereof of the Periodic Table of Elements, which comprises, contacting, in a hydrorefining zone, said heavy oil with hydrogen and an aluminum alkyl compound, the molar ratio of said aluminum alkyl compound to said metal compounds, claculated as the metal, ranging from about 1:1 to about 100:1, at hydrorefining conditions, including a temperature ranging from about 500.degree. to 1500.degree. F. and a pressure ranging from about 500 to about 3000 psig.
