ABSTRACT:
The invention relates to the hydrogenation of coal which comprises extracting the coal with a solvent at temperatures and pressures above the critical temperature and pressure of the solvent in the presence of hydrogen and an effective amount of catalyst comprising a salt or oxide of a metal which is not a noble metal and which is liquid or solid at the extraction temperature. The gas phase solvent may then be separated from the solid residue and the hydrogenated products condensed therefrom by cooling.
