Abstract
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.
Highlights
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, it has been confirmed that the Baganuur coal is a low rank B2 mark lignite and it is suitable for thermal processing including pyrolysis and thermolysis
The results of pyrolysis experiment of Baganuur coal show that 58.6% of coal organic mass remained as a hard residue after pyrolysis
Summary
The coal of Baganuur deposit have been investigated to determine its technical characteristics, elemental and petrographical maceral compositions. Proceeding from this premise, the coal from Baganuur deposit has been chosen for a much more detailed investigation on thermal processing, including pyrolysis and thermolysis, characterization of obtained solid (hard residue) and liquid products.
