Distribution of nitrogen in hydrocracked in situ shale oil
Crude shale oil from underground in situ retorting of Wyoming oil shale was hydrocracked over a nickel-molybdena catalyst in a single-pass operation at 800/sup 0/F, 1500 psig pressure, and 0.5 vol of oil/(vol of catalyst/h). The liquid product was fractionally distilled into naphtha and heavier oil. The 54 fractions distilling above naphtha were collected at 5/sup 0/F intervals (at 10 mm absolute pressure), and nitrogen percentages were determined on these. The hydrocracking eliminated 98% of the nitrogen from the oil, but the boiling-range distribution of the nitrogen compounds remaining in the oil resembled that of the nitrogenous components in raw shale oil and in hydrocracked gas-combustion shale oil.
