Applications of Young Brown Coals from the Khandinskoe Deposit in Irkutsk Oblast

Abstract

The main characteristics of grade 1B brown coal from the Khandinskoe deposit were determined. These are low-sulfur coals. The bitumen content varies from 1.5 to 17.5%, and the average wax content of bitumen is 61.8%. The concentration of humic acids is 40–70%. The yields of extracts, waxes, and tars from the test coals were determined using various extractants and their characteristics were given. Coal from the Khandinskoe deposit can be a promising raw material for the production of lignite wax, coal–alkali reagents, and humic acid preparations.
