Thermal treatment in liquefaction solvent was applied to Victorian brown coal as pretreatment for liquefaction. This treatment decomposes carboxylic groups in the coal and removes them as CO_2. This paper discusses the effects of the treatment conditions on decomposition of the carboxylic groups and suppression of the scale formation during liquefaction of the coal by this treatment.
