摘要： The production of liquid hydrocarbons from coal is significantly enhanced by alkylating or acylating the coal prior to subjecting the coal to liquefaction conditions. The introduction of aliphatic hydrocarbon radicals or acyl radicals, including carbon monoxide, into the coal structure is believed to permit more of the coal to undergo liquefaction at suitable liquefaction conditions. The alkylation or acylation reactions can be conducted in the presence or absence of added or extraneous catalysts.

摘要： A slurry of coal solids or similar carbonaceous material substantially depleted in mineral-rich particles is prepared for delivery to any desired place of use by introducing particulate coal and a suitable carrier liquid into a slurry preparation zone; passing a stream of slurry from the slurry preparation zone to a liquid-solids separator; returning a concentrated slurry stream from the separator to the slurry preparation zone; and passing a substantially clarified liquid stream from the separator to an elutriation zone, which communicates with and extends downward from the slurry preparation zone, in such a manner as to form an upward directed current in the elutriation zone. The velocity of the upward directed current is adjusted so that the heavy mineral-rich particles, which enter the slurry preparation zone with the particulate coal, pass downward through the upward directed current into a collection zone thereby resulting in the formation of a slurry in the slurry preparation zone which is substantially depleted in mineral-rich particles.
摘要翻译：通过将颗粒状煤和合适的载体液体引入到浆料制备区域中，制备基本上耗尽富含矿物质的颗粒的煤固体或类似含碳材料的浆料，以输送到任何所需的使用地点; 将浆料浆从浆料制备区域传送到液体 - 固体分离器; 将浓缩的浆料流从分离器返回到浆料制备区; 并将来自分离器的基本上澄清的液体物流从浆料制备区域连通并向下延伸的淘洗区域以使得在淘析区域中形成向上的电流的方式使基本上澄清的液体物流从分离器送出。调节向上电流的速度，使得与颗粒煤进入浆料制备区的重质富含矿物质的颗粒向下通过向上的电流进入收集区，从而导致在浆料制备区，其基本上耗尽了富含矿物质的颗粒。

摘要： Scale formation during the liquefaction of lower ranking coals and similar carbonaceous materials is significantly reduced and/or prevented by pretreatment with carbon dioxide. The carbon dioxide pretreatment is believed to convert the scale-forming components to the corresponding carbonate prior to liquefaction. The pretreatment is accomplished at a total pressure within the range from about 14 to about 68 atmospheres and a carbon dioxide partial pressure within the range from about 14 to about 34 atmospheres. Temperature during pretreatment will generally be within the range from about 100.degree. to about 200.degree. C.
摘要翻译：较低级煤和类似含碳物质的液化过程中的鳞屑形成被二氧化碳预处理显着降低和/或防止。认为二氧化碳预处理在液化之前将成垢组分转化成相应的碳酸酯。预处理在约14至约68个大气压的范围内的总压力和约14至约34个大气压的范围内的二氧化碳分压下实现。预处理期间的温度一般在约100℃至约200℃的范围内。

摘要： A novel process, and the compositions of matter formed thereby, wherein Group II-A metals, or compounds thereof, can be ion-exchanged onto coal, preferably a high rank coal, notably a subbituminous or bituminous coal, by soaking the coal in an alkali solution of a Group I-A metal compound sufficient to incorporate said metal compound, or cation portion thereof, into said coal to form ion-exchange sites, and ion-exchanging, and thereby replacing all or a portion, preferably a portion, of the Group I-A metal cations with said Group II-A metals. Enhanced gasification rates are achieved by gasification of the so-treated coal, or composition which contains both the Group I-A and Group II-A metals, as contrasted with a coal composition otherwise similar except that it contains an equal molar quantity of either a Group I-A metal or Group II-A metal, rather than both Group I-A and Group II-A metals.
