ABSTRACT:
The present invention relates to a catalytic process for converting a solid carbonaceous material, such as coal, to a liquid product in the presence of hydrogen. More particularly, this invention relates to a coal liquefaction process wherein a mixture of coal, bottoms, solvent and a sulfiding agent is subjected to liquefaction conditions in the presence of a catalyst precursor. This catalyst or catalyst precursor is comprised of a thermally decomposable compound of Groups IIB, IVB, VB, VIB, VIIB, and VIII of the Periodic Table of the Elements such as molybdenum.
