Abstract
The possibility to generate acetylene by pyrolysis in hydrogen plasma was determined using thermodynamic calculations taking into account the elemental composition, temperature range, and the C/H ratio for coal samples from six open-cut mines of the coal deposits of Eastern Siberia: the Mugunsky production site of Tulunugol (ZBR coal rank, the Irkutsk Region), Chadan (GZh coal rank, the Republic of Tyva), Zalushansky (D coal rank, the Trans-Baikal Territory), Irbeysky (2BR coal rank, the Krasnoyarsk Territory), Cheremkhovugol (G coal rank, the Irkutsk Region), Kaakhem (G coal rank, the Republic of Tyva). Results of thermodynamic calculations for the listed coal samples demonstrate the possibility to obtain acetylene from all the six coal ranks under consideration. These results can be used to develop the technology for obtaining acetylene and other compounds by the hydrogen-plasma pyrolysis of coals from the deposits of Eastern Siberia.
