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 intoaseries of tandem reactors and processing therein, wherein the coal powder,water andcatalyst are added into the first reactor of the series of tandem reactors;and thetemperature and pressure of the series reactors is alternatively arranged insub-criticalstate and supercritical state of water from the first reactor, the totalproduct from theprevious reactor is used as the feed of the next reactor without any furtherseparation.
