Property of upgraded solid and liquid products from Baganuur lignite by thermal reaction with solvent
Keywords:low rank coal, petrographic analysis, pyrolysis, thermolysis
The coal of Baganuur deposit have been investigated to determine its technical characteristics, elemental and petrographical maceral compositions. On the basis of proximate, ultimate, petrographic and FTIR analysis, the obtained results have confirmed that the Baganuur coal is a low rank lignite B2 mark. The liquid tar, produced through thermolysis of Baganuur coal, was investigated by FTIR, 13C and 1H NMR spectrometric analysis. The results of thermolysis of Baganuur coal in tetralin has a constant mass ratio between coal and tetralin (1:1.8) at 450°C, which shows that 40.0% of liquid product can be obtained after thermal decomposition of the coal organic mass.
