Naphtha from hydrogenated crude shale oil was suitable for established reforming processes. Good quality no-lead gasoline with an octane number of 89 was made from the naphtha. The octane number and low nitrogen and sulfur content of gasoline from shale oil compared favorably with regular gasolines. Regular grade gasolines now using lead additives have octane ratings near 94. The reforming feed was twice treated with hydrogen. Over 90 percent of the nitrogen and sulfur compounds (which usually inactivate the catalysts used in present reforming processes) was removed from the shale oil during the first hydrogenation step with a cobalt- molybdate catalyst. The relatively "clean" naphtha was then hydrogenated in the presence of nickel-tungsten catalyst, lowering the nitrogen content to 7 ppm of the gasoline and lowering the sulfur content to less than 0.001 Weight-percent. Preselected ranges of temperature and pressure within the commercial reforming ranges were chosen for investigation, with other possible variables held constant.
