Composition of Primary Coal Tar Fractions in Coke Production at Shubarkol Komir

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.
