Low concentrations of Group VIB metal salts of fatty acids will catalyze the hydroconversion of sulfur-containing heavy petroleum oils producing a lighter oil fraction having a lower sulfur concentration than the heavy oil and a tar fraction containing a higher sulfur concentration than the heavy oil. Catalyst concentrations of 300 to 1,000 ppm, calculated as the elemental metal, are used. Molybdenum octoate is a preferred catalyst.
