Catalytic hydroconversion of a relatively heavy hydrocarbon residual fraction is effected by adding a thermally decomposable metal compound to the oil, along with an acidic catalyst solid to the oil, and passing the mixture to a hydroconversion zone containing hydrogen at an elevated temperature. Preferred metals are cobalt and molybdenum. Preferred solids are large pore zeolites, silica/alumina, clays and surface activated metal oxides.

In a process for hydroconverting a heavy natural or synthetic oil charge stock by reacting the oil with hydrogen in the presence of a solid, acidic catalyst after adding to the oil a thermally decomposable metal compound of a metal of Group IVB, VB, VIB, VIIB or VIII of the Periodic Table of Elements, the compound being added in an amount equivalent to 10 to 950 ppm, calculated as the elemental metal, based on the oil feed, the improvement comprising adding a zeolite having an alpha value of at least 1 and a Constraint Index of less than 1 without active metal on the catalyst, to the oil feed having a Conradson carbon content in excess of 1 weight percent, and hydroconverting the oil with the added acidic zeolite catalyst in a hydroconversion zone to convert at least 25 percent of the Conradsen carbon content to lighter materials to form an upgraded oil product.
