Abstract
Attention focuses on the composition of the organic component in coal tar from Shubarkol Komir and its fractions boiling below 150°C and at 170–190 and 220–250°C. Out of the total number of phenols, gas–liquid chromatography identifies only 11 compounds in the coal tar (24.97% of the total tar mass). The presence of 26.15% paraffins (C10–C33) is also established. In the <150°C fraction, the phenol content is 51.53%, and the content of paraffins (C10–C25) is 11.41%. The 170–190°C fraction contains 16.29% phenols and 15.40% paraffins (C10–C26). Finally, the 220–250°C fraction contains 1.47% phenols and 31.45% paraffins (C10–C29). These results confirm that such coal tar may be regarded as a practical source of valuable aromatic hydrocarbons.
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.
