Abstract
This invention is directed to a process for pretreating coal preliminary to a primary liquefaction or hydroconversion block. In the process, a coal feed, slurried in a solvent, is reacted with carbon monoxide in the presence of a chemical promoter at an elevated temperature and pressure. The promoter enhances the depolymerization and hydrogenation of the coal during pretreatment.
