    摘要： Coal is processed by liquefying the coal with a hydrogen-donor solvent under a short-contact-time liquefaction, separating the coal liquid effluent into liquid phases of distinct polarity and an undissolved coal residue, upgrading a portion of the liquid phase, gasifying the residue and high polarity coal liquid to produce a synthesis gas which is used to form methanol. The methanol is catalytically converted to gasoline products. Solvents for liquefaction and effluent separation can be derived from the upgraded liquid phase, methanol and gasoline products. Hydrogen for liquefaction, methanol synthesis and upgrading is derived from the synthesis gas.

    摘要： A method is described to improve a coal liquefaction process by the use of a recycle solvent comprised of two fractions: the first, a lower boiling fraction, is obtained by an atmospheric distillation and is subsequently hydrotreated to enrich its hydrogen donor capacity; the second is a higher boiling fraction that is enriched in desirable hydrogen transfer agents by a solvent extraction process. The combined recycle solvent thus obtained is more efficient in transferring gas phase H.sub.2 to the coal and enables other significant process improvements.

    摘要翻译： 描述了一种通过使用由两个馏分组成的循环溶剂来改善煤液化过程的方法：首先通过常压蒸馏获得较低沸点馏分，随后加氢处理以富集其供氢能力; 第二个是通过溶剂萃取方法富集需要的氢转移剂的较高沸点馏分。 由此获得的组合的再循环溶剂在将气相H 2转移到煤中更有效，并且能够进行其它显着的工艺改进。

    摘要： Catalytic hydroconversion of a relatively heavy hydrocarbon residual fraction is effected in the presence of a lighter oil fraction by adding a thermally decomposable metal compound to the oil, along with an acidic catalyst solid to the oil, and passing the mixture to a hydroconversion zone containing hydrogen at an elevated temperature. Preferred metals are cobalt and molybdenum. Preferred solids are large pore zeolites, silica/alumina, clays and surface activated metal oxides.

    摘要： The invention provides a process for yielding a thermally cracked, demetallated and partially denitrogenated fuel product suitable for upgrading. Coal and highly paraffinic, non-thermally cracked, non-aromatic petroleum residua are combined and heated under controlled conditions to effect the separation of unconverted solids from the resulting liquid effluent. The effluent is then cooled in order to separate out the highly aromatic and polar asphaltenic compounds.

    摘要： Disclosed are methods for upgrading lube oil base stocks comprising the steps of hydrocracking such materials, preferably under relatively moderate conditions, and subsequently separating the hydrocracked materials to produce in an aromatic rich extract stream and an aromatics lean raffinate stream. The separation step is preferably achieved by solvent extraction of at least a portion of the hydrocracked material. The stream comprising the aromatic rich extract is then catalytically cracked under fluidized conditions to produce gasoline and other distillates. The aromatics lean raffinate stream is further processed by dewaxing and/or the like to produce relatively high volume metric yields of low viscosity lube oil having improved viscosity-temperature characteristics.
