A catalyst is prepared by heating the reaction product of CrO3 and tert-butyl alcohol as catalyst precursor in a hydrocarbon medium in the presence of hydrogen sulfide to convert the catalyst precursor to a solid chromium-containing catalyst. Hydroconversion processes utilizing the catalyst to convert oil, coal, and mixtures thereof are also provided.

A process for hydroconverting a carbonaceous chargestock to produce a hydroconverted, hydrocarbonaceous oil product which comprises: reacting said carbonaceous chargestock with hydrogen in the presence of a catalyst at hydroconversion conditions, said catalyst having been prepared by the steps which comprise: (a) forming a mixture of a hydrocarbon material and the reaction product of CrO3 and tert-butyl alcohol, said reaction product having been obtained by reacting tert-butyl alcohol with CrO3 at ambient temperature, and (b) heating the resulting mixture in the presence of a hydrogen sulfide-containing gas at conditions, including a temperature of at least about 500°F. and a total pressure ranging from about 50 to 5000 psig, to produce a slurry comprising said hydrocarbon material and a solid chromium-containing catalyst.
