  • Patent number: 4434045
    Abstract: An improved process for hydrocracking petroleum residuals wherein total conversion and the yield of lower boiling range products are increased. The hydrocracking is accomplished in the presence of a hydrogen donor solvent and molecular hydrogen. The conversion is accomplished at a pressure within the range from about 1500 to about 2500 psig and at a temperature within the range from about 800.degree.to about 850.degree. F. Operation at these conditions is essential to achieving the increased conversion and the increased yield of lower boiling liquid products.While the present invention has been described and illustrated by reference to particular embodiments thereof, it will be appreciated by those of ordinary skill in the art that the same lends itself to variations not necessarily illustrated herein. For this reason, then, references should be made solely to the appended claims for purposes of determining the true scope of the present invention.

  • Patent number: 4338182
    Abstract: An improved process for liquefying coal and similar solid carbonaceous materials wherein the liquefaction is accomplished in a plurality of zones or stages and wherein the temperature is increased either linearly or nonlinearly in the first zone or stage, aromatics which are produced, liberated or contained in the solvent are separated after the first zone or stage and the liquefaction is continued in at least one other stage, at a temperature at least as high as the final temperature in the first zone or stage. In a preferred embodiment, the temperature in the first stage will be increased at least 50.degree. F. The improved process results in a higher conversion of carbon contained in the coal or similar solid carbonaceous material to liquid products.

  • Patent number: 4283267
    Abstract: An increased yield of hydrogenated liquid product is obtained from coal by contacting the feed coal with a hydrogen-donor solvent and a hydrogen-containing gas in a series of two or more liquefaction zones arranged in series and operated in such a manner that the temperature in each zone increases from the initial to the final zone. The effluent from each liquefaction zone is passed to the next succeeding higher temperature zone in the series. Liquid hydrocarbonaceous products are recovered from the effluent withdrawn from the last zone. Hydrogen-donor solvent may be produced in the process by catalytically hydrogenating at least a portion of the liquid product from the last liquefaction zone, recovering a liquid fraction from the product of the catalytic hydrogenation and separating a hydrogen-donor solvent from the liquid fraction.

  • Patent number: 3958957
    Abstract: Methane is produced by contacting a mixture of carbon monoxide or carbon dioxide and hydrogen with a carbon-alkali metal catalyst at a temperature in the range between about 800.degree.F. and about 1500.degree.F. and at a pressure between about atmospheric and about 2000 psig. The catalyst employed may be prepared by heating an intimate mixture of coal, coal char, coke or other carbonaceous solids and an alkali metal salt, hydroxide or similar constituent. Such a catalyst promotes the methanation of carbon monoxide and carbon dioxide and the formation of higher hydrocarbons by the Fischer-Tropsch reaction and at the same time is resistant to high temperature sintering and poisoning by sulfur compounds present in the feed gas. The catalyst can be regenerated if necessary by air oxidation.
