Hydrogenation process |
(57) Active sulfur compounds, especially thiols and thiophenols are effective catalysts
for. hydrogen transfer reactions, catalyzing the transfer of hydrogen from aliphatic
and alkylaromatic compounds.A preferred hydrogen donor is shale oil which may be used
as the donor solvent in a coal liquefaction process in which a thiol or thiophenol
is used as a catalyst to promote transfer of hydrogen from the shale oil to the coal.
