- 中文摘要: Depolymerization of an indigenous coal was studied in a variety of solvents at a temperature of 400 ± 10 °C in a hydrogen environment using a micro autoclave reactor for a time duration of 30 minutes. Some aliphatic, aromatic solvents as well as viscous petroleum based oils and pitches were used for evaluating them as liquefaction solvents. Amongst aliphatic solvents, 2-propanol, and amongst aromatics, p-creosol, gave highest yields. Petroleum pitches also proved effective, particularly their blends which caused significant depolymerization of the coal under study leading to formation of liquid products.
