摘要： A method of removing gangue materials from coal characterized by the steps of comminuting and sizing all of the material to have most particles of a size smaller than one hundred microns; slurrying in an alcohol containing 1 to 4 carbon atoms; thereafter separating by settling velocity separation into an overflow stream containing most of the valuable coal products for storage as a fuel or the like and an underflow containing the gangue materials with some larger sized coal particles; thereafter diluting the underflow with alcohol and separating by settling velocity separation or the like into an overflow stream containing the coal for storage and an underflow containing mostly gangue material with some coal particles; separating the alcohol from the gangue materials and returning the alcohol to the process. The gangue materials can be employed as a fuel if they contain enough of the entrained coal particles. Preferably, the comminution to effect mostly particles smaller than 100 microns is effected by a multi-step process including crashing and screening to drying size: drying: and separating into top and bottom streams, the hot latter being sent to a thermal-chemical reactor employing cool alcohol and thermal shock to effect partial comminution; and further comminution to effect the particle sizes less than 100 microns. Also disclosed are specific details of the process to effect a low cost non-polluting carbonaceous fuel feed stock or hydrocarbon fuel extender.
