ABSTRACT OF THE DISCLOSURE An improved process for the hydroconversion of coal comprising pretreating coal in an aqueous carbon monoxide-containing environment, followed by extracting a soluble hydrocarbon material from the coal, and subsequently hydroconverting the extracted material in a hydroconversion reactor. The extracted material consists of a relatively hydrogen-rich mate- rial which is readily converted to valuable liquid products in high yield. The residue from the extrac- tion stage is relatively hydrogen deficient material which can be gasified to produce hydrogen and carbon monoxide for the hydroconversion and pretreatment stages, respectively.
