Abstract
The structural features of anthracite are investigated by infrared (IR) and Raman spectroscopy. Three anthracite samples from the Bungursky, Krasnogorsky, and Listvyansky mines are studied. Their vitrinite reflection coefficient varies from 2.58 to 5.26%. Analysis of IR spectroscopic data shows that the anthracite with the largest vitrinite reflection coefficient (the Listvyansky sample) has the greatest aromatic parameters (fa, AR1, and AR2). Its organic mass contains shorter and more branched aliphatic side chains, as confirmed by the low CH2/CH3 ratio. Raman analysis confirms that ordered graphite-like structural fragments predominate in the Listvyansky anthracite
期刊介绍:
The journal publishes scientific developments and applications in the field of coal beneficiation and preparation for coking, coking processes, design of coking ovens and equipment, by-product recovery, automation of technological processes, ecology and economics. It also presents indispensable information on the scientific events devoted to thermal rectification, use of smokeless coal as an energy source, and manufacture of different liquid and solid chemical products.
