;
In-situ crude shale oil, produced by the underground combustion retorting method, was hydrocracked over a nickel--molybdena catalyst at 800/sup 0/F and 1500 psig. The liquid product was distilled into a low-octane reforming feedstock amounting to 18.5 vol percent of the in-situ crude plus a large number of small volume higher boiling fractions and a small quantity of waxy residuum. Most of the small volume distillate fractions were blended into types C-B, T-T, and S-M diesel fuels whose properties resembled those of diesel fuels and distillate fuels now being marketed. The diesel fuels also met the ASTM requirements for diesel fuels and distillate fuel oils with minor exceptions. The dewaxed residuum was blended with a portion of the small volume distillate fractions to form a fuel oil fitting the requirements for No. 4 fuel oil with the exception that its viscosity was between the viscosity limits for No. 2 and No. 4 fuels. The yield of diesel fuels was 51.64 vol percent of the in-situ crude, and the yield of No. 4 fuel oil was 21.64 vol percent, for a total of 73.15 vol percent in the in-situ crude that could be used as low-sulfur diesel fuels or Nos. 1 through 4 burner fuels.
