International Coal Refining Company, MCFADDEN FINCHAM, October 23, 1984: CA1176588

ABSTRACTThere is described an improved liquefaction processby which coal is converted to a low ash and low sulfurcarbonaceous material that can be used as a fuel in anenvironmentally acceptable manner without costly gasscrubbing equipment. In the process, coal is slurriedwith a solvent, passed throu ...
