Abstract

The present research work deals with the behavior of the thermal decomposition of the coals from Shivee-Ovoo and Tavantolgoi deposits and the determination of the kinetic parameters of their thermal decomposition. Thermal decomposition experiments were performed at five different heating temperature rates (10, 20, 30, 40, 50 ℃/min) for two typical rank coal such as bituminite and lignite samples in an argon atmosphere temperature range from 25 ℃ to 1000 ℃. The experimental results of thermogravimetric analysis of both Shivee-Ovoo and Tavantolgoi coal samples show that the heating rate increases weight loss was decreased as well as the maximum decomposition rate was slightly increased. First-time kinetic parameters such as activation energy and pre-exponential factor were calculated using model-free methods like Kissinger, Friedman and KAS for the Shivee-Ovoo and Tavantolgoi coal samples. The arithmetic average of activation energies calculated by the Kissenger, Friedman and KAS methods were 157.9, 188.6, and 203.6 kJ/mol for Shivee-Ovoo and 227.05, 129.2, and 131.1 kJ/mol for Tavantolgoi coal, respectively.
