- An envelope of parameter values has been experimentally identified in our laboratory, heretofore unexplored, for the catalytic depolymerization of coal which leads to yields of C[sub 2]-C[sub 4] hydrocarbons in excess of 50 weight percent of the coal, in a direct, single-stage process under mild conditions. The chemistry observed is fundamentally different from all coal conversion processes, both liquefaction and gasification, previously reported in the literature. The process-derived recycle liquid solvent will be characterized, and is expected to constitute a super-critical phase under conditions of temperature and pressure imposed by the chemistry of the system. Using a special reactor incorporating windows for visual observation, the operation of a catalyst bed fluidized by super-critical, coal-derived fluids will be examined. The capability of such a supercritical, coal-derived fluid to control agglomeration of a strongly caking coal, in the catalyst bed, will be evaluated, and satisfactory control developed. Solvent upgrading of the recycled liquids will be applied as may be required.
