An improved process is described for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands. The charge oil in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone, and the effluent emerging from the top of the zone is separated into a gaseous stream containing a wide boiling range material and a liquid stream containing heavy hydrocarbons. According to the novel feature, the charge stock is in the form of a slurry of heavy hydrocarbon oil and finely divided fly ash or high ash coal fines. The presence of this ash in the charge stock serves to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone.
