Abstract

PURPOSE: Undried brown coal is mixed with a solvent to form a slurry, which is subjected to dehydration treatment to provide a slurry suitable for the liquefaction operation and concurrently the steam generated on the dehydration treatment is utilized as the heat source for preheating the slurry to improve heat economy.
