Abstract:
A process of catalytic hydroconversion of a heavy hydrocarbon oil containing a substantial portion of components having am atmospheric boiling point above about 565.degree. C. (1059.degree. F.) to give a product hydrocarbon oil containing a substantial portion of components having a boiling point below about 565.degree. C. (1050.degree. F.), the process comprising:mixing the heavy hydrocarbon oil with an oil soluble molybdenum compound, wherein the molybdenum compound has a first decomposition temperature of at least 222.degree. C. (431.degree. F.), to give a mixture having from about 0.005 to about 0.050 weight percent molybdenum compound, wherein said mixture consists essentially of the heavy hydrocarbon oil and the oil soluble molybdenum compound;introducing the mixture into a hydroconversion zone, the hydroconversion zone being at a temperature from about 343.degree. C. (650.degree. F.) to about 454.degree. C. (850.degree. F.) and a total pressure from about 6996 kPa (1000 psig) to about 24,233 kPa (3500 psig) and containing heterogeneous catalyst, the catalyst including a Group VIII non-noble metal oxide, and a Group VI-B metal oxide on an alumia or silica-alumina support;introducing a reactor feed gas into The hydroconversion zone, the reactor feed gas including a majority of hydrogen gas, the introducing being conducted at a rate from 356.2 liters (H.sub.2) / liters(oil) (2000 standard cubic feet (H.sub.2) / Barrel (oil)) to about 1781.2 liters (H.sub.2) / liters(oil) (10,000 standard cubic feet (H.sub.2) / Barrel (oil)); and,recovering the product hydrocarbon oil from the hydroconversion zone.
