COAL PROCESSING METHOD BY USING CHARACTERISTIC OF SUB-CRITICAL AND SUPERCRITICAL WATER

摘要

A coal processing method includes adding coal powder, water and catalyst into a set of series reactors and processing, wherein the coal powder, water and catalyst are added to the first reactor of the set of series reactors, the temperature and pressure of the series reactors is alternately arranged in sub-critical state and supercritical state of water from the first reactor, the total product from the previous reactor is used as the feed of the next reactor without further separation.
