Coal Liquefaction and Characterization of Coal-derived Oils Using the Direct Liquefaction Test Plant

Journal of the Fuel Society of Japan, 1981
The liquefaction of four coals (Yallourn, Soya-koishi, Taiheiyo, and Shin-yubari coals) with different coal ranks has been made by using the 0.1 tjd direct liquefaction test plant.The low rank coals generally produced larger CO, CO2 and H2O, derived from oxygen present in coal.The hydrogen consumption decreased linearly with the increase in the coal ...
