    • Process for producing fluid fuel from coal using a hydrogen-donor solvent as an extractant. Moisture-free, preheated coal in particulate form is contacted in a drum with hot solvent to extract the hydrocarbons therefrom. Subsequently, the pressure is released to vaporize the solvent and at least a portion of the hydrocarbons extracted. The temperature of the mass in the drum is then raised under conditions required to crack the hydrocarbons in the drum and to produce, after subsequent stripping, a solid coke residue. The hydrocarbon products are removed and fractionated into several cuts, one of which is hydrotreated to form the required hydrogen-donor solvent while other fractions can be hydrotreated or hydrocracked to produce a synthetic crude product. The heaviest fraction can be used to produce ash-free coke especially adapted for hydrogen manufacture. The process can be made self-sufficient in hydrogen and furnishes as a by-product a solid carbonaceous material with a useful heating value.
    • 使用氢供体溶剂作为萃取剂从煤生产流体燃料的方法。 颗粒状的无水,预热的煤在滚筒中与热溶剂接触以从其中提取烃。 随后,释放压力以蒸发溶剂,并提取至少一部分烃。 然后将滚筒中的质量的温度在裂化滚筒中的烃所需的条件下升高,并在随后的汽提之后产生固体焦炭残余物。 将烃产物除去并分级成几个切口,其中一个切割加氢处理以形成所需的氢供体溶剂,而其它部分可以被加氢处理或加氢裂化以产生合成粗产物。 最重的馏分可用于生产无灰焦炭,特别适用于制氢。 该方法可以在氢气中自给自足,并作为副产物提供具有有用加热值的固体含碳材料。

    • Process for producing fluid fuel from coal. Moisture-free coal in particulate form is slurried with a hydrogen-donor solvent and the heated slurry is charged into a drum wherein the pressure is so regulated as to maintain a portion of the solvent in liquid form. During extraction of the hydrocarbons from the coal, additional solvent is added to agitate the drum mass and keep it up to temperature. Subsequently, the pressure is released to vaporize the solvent and at least a portion of the hydrocarbons extracted. The temperature of the mass in the drum is then raised under conditions required to crack the hydrocarbons in the drum and to produce, after subsequent stripping, a solid coke residue. The hydrocarbon products are removed and fractionated into several cuts, one of which is hydrotreated to form the required hydrogen-donor solvent while other fractions can be hydrotreated or hydrocracked to produce a synthetic crude product. The heaviest fraction can be used to produce ash-free coke especially adapted for hydrogen manufacture. The process can be made self-sufficient in hydrogen and furnishes as a by-product a solid carbonaceous material with a useful heating value.
    • 从煤生产流体燃料的方法。 颗粒形式的无水煤与供氢剂溶剂一起制浆,并将加热的浆料装入鼓中,其中调节压力以保持一部分溶剂为液体形式。 在从煤中提取烃时,加入另外的溶剂以搅拌鼓料并保持其达到温度。 随后,释放压力以蒸发溶剂,并提取至少一部分烃。 然后将滚筒中的质量的温度在裂化滚筒中的烃所需的条件下升高,并在随后的汽提之后产生固体焦炭残余物。 将烃产物除去并分级成几个切口,其中一个切割加氢处理以形成所需的氢供体溶剂,而其它部分可以被加氢处理或加氢裂化以产生合成粗产物。 最重的馏分可用于生产无灰焦炭,特别适用于制氢。 该方法可以在氢气中自给自足,并作为副产物提供具有有用加热值的固体含碳材料。
