ABSTRACT:
A process for converting coal, comprising, subjecting a slurry composed essentially of coal, a hydrocarbon solvent and a hydrogenation catalyst to primary hydrogenation to liquify the coal, separating the ash content of said coal from the reaction product thereby obtaining a liquified product, subjecting at least a portion of the liquified product to secondary hydrogenation in the presence of a hydrogenation catalyst thereby converting the liquified product to light oil product, the secondary hydrogenation step being a point of supply of hydrogenation catalyst to the coal conversion system, separating the hydrogenation catalyst from the reaction product of the secondary hydrogenation step, and returning said separated hydrogenation catalyst to the primary hydrogenation step where it is used as the catalyst for primary hydrogenation of said slurry.
