摘要
采用热重分析仪,考察了3种典型煤种的气化反应特性;利用缩核芯模型,模拟了3种煤的气化过程,并对拟合结果进行了分析。结果表明:随气化温度的升高,3种煤的气化反应性均增加;3种煤的气化反应性大小次序为无烟煤<烟煤<褐煤;3种煤的气化反应活化能分别为褐煤124.9 k J/mol、烟煤154.3 k J/mol、无烟煤100.7 k J/mol;缩核芯模型适用于褐煤和烟煤的气化,但不适用于无烟煤。
The gasification reactivity of three coals were investigated using a thermogravimetric analyzer. The shrink core model was used to simulate the gasification process. The fitting results of the three coals were also analyzed. The experimental results show that the reactivity of the three coal increases as the temperature increases. The reactivity of lignite was higher than that of bituminous and anthracite. The activation energy of lignite, bituminous and anthracite during gasification were 124.9 kJ/mol, 154.3 kJ/mol and 100.7 kJ/mol, respectively. The shrink core model was suitable for the gasification of lignite and bituminous, but not for the anthracite.
