采用填充床热天平反应器（ＰＢＢＲ）系统，于０．０９８ＭＰａ～２．４５ＭＰａ压力和７５０℃～１０００℃温度下进行了煤焦与水蒸气气化反应的活性研究，以基碳转化率（Ｘ）和比气化速率（Ｂ）作为反应活性的评价指标。结果表明，煤焦的Ｘ和Ｂ随着温度和压力的增加而增加；煤焦的气化反应活性顺序为：褐煤焦＞气煤焦＞贫煤焦。
The gasification reaction of coal char and steam was carried out at a pressure of 0.098MPa ~ 2.45MPa and a temperature of 750 ~ 1000 ℃ with a packed bed thermobalance reactor (PBBR) ) And specific gasification rate (B) as reactivity indicators. The results showed that the X and B of coal char increased with the increase of temperature and pressure. The gasification reactivity of coal char was in the order of lignite char> coal char> lean char.
