Thermal treatment decomposing carboxylic groups of brown coal in the process solvent is effective to suppress the formation of carbonate scale in the latter liquefaction section. The process reliability is expected to be further improved with that pretreatment. The influence of pretreatment temperature and solvent species to liquefaction yield is studied in this paper.
