摘　　要：采用自制实验装置研究了煤粉残炭二氧化碳的反应性 ,研究结果表明 :煤粉残炭二氧化碳反应性随原煤挥发份增加而增加 ,随残炭制备温度增加而增加 ,随煤粉粒度增加而下降 ;焦炭的二氧化碳反应性低于煤粉残炭二氧化碳的反应性 .The reactivity of residual char of pulverized coal with carbon dioxide has been investigated in the self make equipment. The results indicated that the reactivity of residual char is increase with increase of coal volatile and preparation temperature for residual char, decreases with increase of pulverized coal size. The coke reactivity is smaller than that of residual char. According to the results, the relative active index and the experience formulation of forecasting residual active index have been put forward.
