Method of coal liquefaction

摘要

A method of coal liquefaction comprising the steps of: (a) producing a coal slurry from a pulverized coal and a solvent; (b) compressing a coke oven gas to prepare a compressed gas; (c) reacting the coal slurry with the compressed gas in a reactor under a high pressure and high temperature condition to form a liquefied product; (d) separating the liquefied product into a used gas and a liquefied slurry; and (e) distillating the liquefied slurry to form a liquefied oil and a solvent refined coal.
