Crude shale oil produced during in situ retorting by the Bureau of Mines at Rock Springs, Wyoming, was refined by three schemes. In the first, the crude oil was fractionated to raw naphtha and 400 degrees F residuum. The residuum was hydrogenated over cobalt molybdate catalyst at 815 degrees F and 1100 psig. The blended raw and 160-400 degrees F hydrogenated naphthas were hydrodenitrified and then catalytically reformed. The 400 degrees F hydrogenated oil was catalytically cracked. In the second scheme, the crude was hydrogenated over nickel-tungsten catalyst at 800 degrees F and 1500 psig. The hydrogenated fractions were processed by methods used in the first scheme. The third scheme resembled the second but, prior to hydrogenation, the crude was "hydrostabilized" over cobalt molybdate at 500 degrees F and 500 psig. Yields of reformate and cat-cracked gasoline as volume-percents of the crude, and research-method octane numbers for the three methods were as follows: First method, 32 pct reformate, 90 octane; 19.5 pct cracked gasoline, 99.2 octane. Second method, 29 pct reformate, 81.1 octane; 21.3 pct cracked gasoline, 99.6 octane. Third method, 28.2 pct reformate, 86 octane; 28.7 pct cracked gasoline, 95.9 octane.
