Abstract

Direct liquefaction of Mukah Balingian coal was successfully carried out using tetralin, glycerol and tetralin-glycerol mixed solvent system in a batchwise reactor system. This study aimed to determine the effect of tetralin-glycerol mixed ratio, liquefaction temperature and reaction time on coal conversion and percent of products yield. Tetralin, being an excellent hydrogen donor solvent, showed high conversion of 85 wt.% with 75.13 wt.% of oil+gas. However, it was revealed that usage of glycerol alone at a high temperature of 420 °C is not possible due to the production of high molecular weight of polymerised residue.
