    • An improved process for converting coal to liquid and gaseous products wherein the liquid products predominate and wherein reactor, tubing, and valve plugging due to carbonate salt formation is reduced by reacting crushed low-rank coal containing about 12 to 30% by weight of water in a solvent at a temperature in the range of about 455.degree. to 500.degree. C., under about 2000 to 5000 psi pressure of a H.sub.2 /CO mixture for a liquid residence time of about 20 to 60 minutes. The solvent is a fraction of liquid product defined on a weight basis as being made up of about 55% of which distills at less than 250.degree. C./lmm, about 20% of which is soluble in THF, and about 25% of which is carbon polymer and indigenous inorganic matter. The solvent is further defined as containing at least about 5 weight % of partially hydrogenated aromatics and/or fully hydrogenated aromatics and little or no alkylated aromatics or higher alkanes.
    • 将煤转化为液体和气态产物的改进方法,其中液体产物占主导地位,并且由于碳酸盐形成导致的反应器,管道和阀堵塞通过使包含约12至30重量%的水的粉碎的低级煤 溶剂在约455℃至500℃的温度下,在约2000至5000psi压力下的H 2 / CO混合物,液体停留时间为约20至60分钟。 溶剂是以重量为基准定义的液体产物的一部分,由约55%的蒸馏物组成,其中小于250℃/ l,其中约20%可溶于THF,其中约25% 是碳聚合物和本土无机物质。 溶剂进一步定义为含有至少约5重量%的部分氢化芳族化合物和/或完全氢化的芳族化合物,很少或没有烷基化芳族化合物或高级烷烃。
