Method for the beneficiation, liquefaction and recovery of coal and other solid carbonaceous materials

摘要

An integrated, continuous (or batch) process for the beneficiation and/or liquefaction of coal, especially low rank coals, is provided, the process generally involving admixing coal with an organic liquid medium under high shear agitation, further beneficiating the coal by admixing the same in an aqueous medium optionally containing a monomer and a polymerization catalyst therefor and subjecting the resultant coal product to further high shear agitation in the presence of certain organic liquid media to provide a liquefied coal extract product and a further solid coal product. Beneficiated solid and liquefied coal products are also provided.
