Abstract
Abstract A catalytic slurry process for hydrorefining a hydrocarbonaceous charge stock containing hydrocarbon-insoluble asphaltenes. The process is effected in slurry fashion with the charge stock being admixed with a phenolic solution of a tetravalent vanadium salt. The slurry is reacted at conditions including a temperature above about 225* C. and a pressure greater than about 500 p.s.i.g., and in the presence of hydrogen and hydrogen sulfide.
