A process for converting a heavy hydrocar- bonaceous chargestock to lower boiling products which process comprises reacting the chargestock with a catalyst concentrate in the presence of hy- drogen, at hydroconversion conditions, said ca- talyst concentrate having been prepared by the steps comprising: (a) farming a precursor catal- yst concentrate by mixing together: (i) a hydro- carbonaceous oil comprising constituents boiling above about 570 °C(ii) a metal compound; said metal being selected from the group consisting of Groups II, III, IV, V, VIIB, VIIB and VIII of the Periodic Table of the Elements, in an amount to provide from about 0.2 to 2 wt. % metal, based on said hydrocarbonaceous oil; and (b) heating the precursor concentrate to an effective temperature to produce a catalyst concentrate, wherein ele- mental sulfur is used as the sulfiding agent in an amount such that the atomic ratio of sulfur to metal is from about 1/1 to 8/1.
