ABSTRACT OF THE DISCLOSURE An improved process for the hydroconversion of coal, wherein coal is slurried in an organic solvent and subjected to pretreatment with carbon monoxide, followed by separation of a solvent-soluble phase comprising hydrocarbon material from the coal, and subsequently hydroconverting the extracted material in a hydroconversion reactor. The extracted material consists of a relatively hydrogen-rich material which is readily hydroconverted to valuable liquid products in high yield. The coal residue is relatively hydrogen deficient material which can be gasified to produce hydrogen and carbon monoxide for the hydroconversion and pretreatment stages, respectively.
