Abstract: A process for upgrading oil feedstock wherein the feedstock is hydrocracked, flashed and/or distilled. The bottoms are then vacuum distilled to adjust viscosity and volatility. The refined feed is then dewaxed under high pressure by a medium pore molecular sieve. The dewaxed material is then cascaded to a hydrofinishing step, where it is contacted with an aromatics saturation catalyst having a metal hydrogenation function in order to produce, after appropriate flashing and distillation, lubricant products having high Viscosity Index, low aromatics content, low volatility and excellent stability to light in the presence of oxygen.

Abstract: A process for upgrading oil feedstock wherein the feedstock is hydrocracked, and flasked and/or distilled. A distillate fraction boiling in the diesel range is isolated and dewaxed under high pressure by a medium pore molecular sieve. The dewaxed material is then cascaded to a hydrofinishing step, where it is contacted with an aromatics saturation catalyst having a metal hydrogenation function in order to produce diesel fuels having low aromatics content.

Abstract: Particulate coal is rendered less subject to spontaneous ignition by simultaneously spraying or otherwise contacting it and cooling it with an aqueous emulsion in water of a light cycle oil, heavy cycle oil, clarified slurry oil, durene, and other carbonaceous materials derived from coal liquefaction and petroleum refining. Aqueous polymer emulsions and oxidation inhibitors can also be used.

Abstract: Particulate coal is rendered less subject to spontaneous ignition by simultaneously spraying or otherwise contacting it and cooling it with an aqueous emulsion in water of foots oils, petrolatum filtrate, or hydrocracker recycle oils in water.

Abstract: Coal is rendered less subject to abrasion and disintegration by reducing it to a 0.2 to 0.5-inch particle size and drying it at a temperature of 200.degree. to 230.degree. F. for 3-7 minutes. The coal is rendered less susceptible to spontaneous ignition by the application of a treating agent which is a petroleum resid mixed with clarified slurry oil or a petroleum resid mixed with a distillate.

Abstract: Particulate coal is rendered less subject to spontaneous ignition by spraying or otherwise contacting it with a light cycle oil, heavy cycle oil, clarified slurry oil, a solution of durene in gasoline and mixtures of two or more of the preceding.

Abstract: Coal is rendered less subject to abrasion and disintegration by reducing it to a 0.2 to 0.5-inch particle size and drying it at a temperature of 200.degree. to 230.degree. F. for 3-7 minutes. The coal can be rendered less susceptible to spontaneous ignition by the application of a treating agent which can be a light cycle oil, heavy cycle oil, clarified slurry oil, a petroleum or coal derived distillate or residuum, a solution of durene in gasoline and mixtures of two or more of the preceding.

Abstract: Coal is rendered less subject to abrasion and disintegration by reducing it to a 0.2 to 0.5-inch particle size and drying it in a drying zone at a temperature of 200.degree. to 230.degree. F. for 3-7 minutes while simultaneously applying a treating agent which can be a light cycle oil, heavy cycle oil, clarified slurry oil, a petroleum or coal derived distillate or residuum, a solution of durene in gasoline and mixtures of two or more of the preceding.
