Abstract

This invention is directed to a staged process for producing liquids from coal or similar carbonaceous feeds combining a pretreatment stage and a liquefaction stage. In the process, the feed is dispersed in an organic solvent and reacted with carbon monoxide at an elevated temperature and pressure. The so pretreated coal is sent to a liquefaction reactor, wherein the coal is reacted in the presence of hydrogen and catalyst to produce valuable liquid fuels or feedstocks.
