ABSTRACT:
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.
