  • Coal Liquefaction process employing octahydrophenanthrene-enriched solvent
    Patent number: 4323447
    Abstract: A coal solvation/liquefaction process wherein the coal is contacted with hydrogen and an octahydrophenanthrene-enriched solvent containing OHP and THP in a ratio of OHP/THP greater than 0.4, wherein the OHP is present in an amount of at least 5 percent by weight based upon the total weight of said solvent.The OHP-enriched solvent provides improved coal solvation and increases the production of distillate liquid (62) in a coal solvation/liquefaction (20, 24) process. The desired ratio of OHP/THP is provided by catalytic hydrogenation (68) of a coal liquid distillate stream (64). By increasing the OHP/THP ratio to a value greater than 1, the amount of hydrogen consumed in the process can be significantly reduced.

  • Subterranean gasification of bituminous coal
    Patent number: 4313499
    Abstract: In the underground gasification of a swelling coal the high gas-flow link between the injection and the production wells needed for the gasification process is produced by reverse combustion using air heated to a temperature below the softening point of the coal. The heated air pretreats and conditions the coal proximate to the link under formation by increasing its permeability and reducing its swelling properties. Improved combustion and suppression of plugging results in the subsequent gasification stage.
