摘要：
Liquefaction of liptobiolith coal in steam and supercritical water flow at a constant increase in the temperature from 300 to 470°C is studied. Temperature dependences of the yield of liquid and volatile products and apparent kinetic parameters of the process are obtained. The yields of oil, resin, asphaltene, and volatile products are determined to be 23.2, 16.1, 5.1, and 14.1% of the coal organic matter (COM), respectively. The participation of water molecules in thermochemical transformations of COM results in a 13.2 wt % increase in the amount of oxygen in the conversion products and residue.
