| 英文摘要 | The combustion characteristics of chars derived from a bituminous coal (Datung, also denoted as DT) at different pyrolysis temperatures were studied via simultaneous thermal analysis (STA). The chars were obtained at pyrolysis temperatures of 550, 650, 750,and 850 degrees C. The carbon structure of chars and the parent coal were characterized using X-ray diffraction. Pore structures of chars and parent coal were measured by nitrogen adsorption. Based oil the thermogravimetric analysis results, the ignition behavior and reactivity of the chars and the parent coal, as well as those of Yangquan (YQ) anthracite, were compared. The ignition temperature (T-i) and weighted mean apparent activation energy (E-m) were obtained and used to evaluate reactivity. The results show that the ignition type of the bituminous parent coal and chars derived at 550, 650, and 750 degrees C is predominately hetero-homogeneous, whereas that of char derived at 850 degrees C and the YQ anthracite is heterogeneous. Thermal deactivation was observed under the pyrolysis conditions in this work. The reactivity of all chars is lower than that of the parent coal but higher than that of Yangquan anthracite. Moreover, the char that was derived at 650 degrees C has the highest reactivity among all chars. Carbon structure ordering contributes more to the thermal deactivation at high temperatures than at low temperatures. Changes in pore structure and material composition affect the reactivity for chars derived from both low and high temperatures. |
