Until recently refiners avoided the upgrading of residual fuels by catalytic hydrogenation. The difficulties experienced in the development of the catalytic desulfurization of residual fuels demonstrated the infeasibility of such a process. It is far more practical to selectively extract only the asphaltene-free portion of the coal and use the remaining undissolved coal for the production of H/sub 2/ and energy. Furthermore, this could prove to be an additional advantage if such a selective solvent could also simultaneously promote the transfer of H/sub 2/ from the gas phase to the coal eliminating the use of hydrogenation catalysts which, in coal hydrogenation, adds tremendously to the cost of coal liquefaction. Such a solvent has been found and is discussed including the relationship of coal liquefaction with crude oil processing.
