    摘要: A method is disclosed for reducing the nitrogen content of oil shale by removing therefrom nitrogen-containing compounds. The nitrogen content of shale oil is reduced by agitating the shale oil with designated amounts of acidified spent oil shale. Acidification is obtained by contacting spent oil shale with sulfuric acid produced by oxidizing hydrogen sulfide emanating from the oil shale retorting process. Agitation of the acidified oil shale with nitrogen-containing oil shale can be either a batch or continuous process. The method also provides for recycling acidified spent shale back into the process for further reduction of the oil shale nitrogen content.

    摘要: The coking tendencies of heavy hydrocarbon feedstocks are reduced by treatment with a free radical removing catalyst such as a transition metal naphthenate, preferably at temperatures below 350.degree. C. The treated product has improved stability as such and may be treated in subsequent processing operations such as catalytic cracking and thermal cracking, including visbreaking and coking, with improved liquid yield and reduced coke production.

    摘要: The nitrogen-containing and oxygen-containing contaminants of a mineral oil are converted to the corresponding sulfur compounds by contacting the oil with a fresh catalyst containing metals from Groups VB, VIB and VIII or a deactivated and metals contaminated hydrodesulfurization catalyst in the presence of hydrogen and hydrogen sulfide under conditions of elevated temperature and pressure.
