A solvent-flowing reactor (SFR) was utilized to examine effects of cooling in batch reactor (BTR) system on conversion of Yallourn coal liquefaction product being soluble in tetralin at a liquefaction temperature into those insoluble in extraction solvents at room temperature. The maximum conversion obtained in SFR was about 70% which was significantly higher than that in BTR. Analyses of the molecular weight distribution of the products as well as dependency of the product yields on liquefaction temperature and time suggested that a portion of the products converts to solvent insolubles along with a decrease in the tetralin solubility upon cooling.
