Pyrolysis Characteristics of Long Flame Coal

Abstract:

Applying thermogravimetry coupled with mass spectrometry, a pyrolysis analysis of a long flame coal from Chinese Hami was carried out. The results show: In the temperature range between 400°C and 600°C, the degradation of the carbonaceous matrix and the evolution of relatively high molecular weight species result in the abundant release of CH₄, C₃H₆, C₆H₆, C₇H₈, C₈H₁₀ and otherwise gas in the coal sample. The weight loss between 400°C and 600°C occupies a main proportion in the total weight loss. In the temperature range between 600°C and 900°C, the condensation of the aromatic ring and the decomposition of mineral matter result in the abundant release of H₂, CO₂, C₆H₆ and otherwise gas.
