Abstract

PURPOSE: To improve the dehydration degree of brown coal, by dehydrating raw brown coal powder in a fluid medium such as superheated steam, etc., at high temperature and pressure, and thereafter, subjecting the treated brown coal to the secondary dehydration by passing the decomposition gas therethrough.
