Abstract
A catalytic hydroconversion process is effected by reacting with hydrogen a heavy hydrocarbonaceous oil containing a catalyst comprising an iron component and a catalytically active other metal component prepared by dissolving an oil soluble metal compound in the oil and converting the metal compound in the oil to the corresponding catalytically active metal component. Preferred oil soluble compounds are molybdenum compounds.

A process for hydroconverting a heavy hydrocarbon oil chargestock, which comprises:
- reacting a heavy hydrocarbon oil chargestock containing a catalyst with hydrogen at hydroconversion conditions in a hydroconversion zone, said catalyst comprising an effective amount of an iron component and a catalytically active metal component selected from the group consisting of Group VB, Group VIB, Group VIIB, Group VIII metals other than iron, of the Periodic Table of Elements, and mixtures thereof, said iron component being added to said oil chargestock as solid particles, and said catalytically active metal component having been prepared by the steps of:
- a. adding to said heavy hydrocarbon oil chargestock an effective amount of an oil soluble metal compound, said metal being selected from the group consisting of Group VB, Group VIB, Group VIIB and Group VIII metals other than iron, of the Periodic Table of Elements, and mixtures thereof, and
- d. converting said oil-soluble metal compound to a catalytically active metal component within said chargestock in the presence of a hydrogen-containing gas.
A process for hydroconverting a heavy hydrocarbon oil chargestock, which comprises:
- a. adding to said oil chargestock a particulate solid iron component and an oil soluble molybdenum compound in an amount ranging from about 25 to about 950 weight parts per million, calculated as elemental molybdenum, based on said oil chargestock;
- b. converting said molybdenum compound and said iron component to a catalyst in situ within said chargestock by reacting the resulting mixture with a hydrogen-containing gas in a hydroconversion zone, at hydroconversion conditions including a temperature ranging from about 416.degree. C. to about 538.degree. C. and a hydrogen partial pressure ranging from about 500 psig to about 5000 psig, and
- c. recovering a hydroconverted oil.
