Disclosed is a catalytic process for hydroconverting heavy hydrocarbonaceous feedstocks to lower boiling products wherein a catalyst precursor concentrate or catalyst concentrate is first prepared in a heavy oil medium then fed to a hydroconversion zone which may also contain a supported hydrotreati

대표청구항 ▼

A hydroconversion process for converting a heavy hydrocarbonaceous oil to lower boiling products, which process comprises the steps of: (a) forming a mixture of a hydrocarbonaceous oil blend comprised of about 22 to about 85 wt.% of a heavy hydrocarbonaceous oil boiling above about 1050°F. with the remainder a lighter hydrocarbonaceous oil, and an oil dispersible, or decomposable, metal compound in an amount ranging from about 0.1 to about 2 weight percent, calculated as elemental metal, based on the weight of said hydrocarbonaceous oil blend, said metal being selected from the group consisting of Groups II, III, IV, V, VIB, and VIII and mixtures thereof, of the Periodic Table of the Elements; (b) heating said mixture in the presence of a sulfiding agent at a temperature of at least about 500°F. for an effective amount of time to convert the oil-dispersible, or decomposable, metal compound to the corresponding metal-containing catalyst thereby forming a catalyst concentrate; (c) introducing at least a portion of said catalyst concentrate into a hydroconversion zone containing a heavy hydrocarbonaceous chargestock and a supported catalyst comprised of (i) a metal selected from Groups VIB and VII of the Periodic Table of the Elements; and (ii) a refractory inorganic support material; (d) subjecting the mixture in the hydroconversion zone to a temperature of about 700°to 900°F., in the presence of an effective amount of a hydrogen-containing gas, at a hydrogen partial pressure from about 100 to 5000 psig, thereby producing lower boiling hydrocarbonaceous products.
