Abstract
The thermolysis of brown coal was carried out at temperatures of 360 and 380°C in water without a catalytic additive and in the presence of a catalyst based on iron oxides, and the composition of the products was studied. It was shown that the use of a catalytic additive in the course of the thermolysis of coal in water led to an increase in the yield of liquid and gaseous hydrocarbons; in this case, the fraction of maltenes in liquid products increased, and the concentrations of hydrogen and carbon oxides in gaseous products increased significantly.
