摘要
在填充床热天平反应器(PBBR)上,于9.8×10~4～24.5×10~4Pa和750～1000℃条件下进行了三种煤焦与水蒸汽的气化反应活性研究。结果表明:煤焦活性随原煤变质程度增加而降低;随着压力提高、煤焦的基碳转化率和比气化反应速率均增加;C_f—H_2O气化反应级数在0.23～0.33范围内;利用Arrhenius方程求得了反应活化能。
The reactivities of gasification on three Chinese coal chars under 1~ 25 atm and 750~1000℃ with steam have first been investigated by using a Packed Bed Balance Reactor (PBBR) in China. The experimental results show: char reactivity decreases with increasing metamorphism of parent coal; base carbon conversion and specific gasification rate increase with elevating gasification pressure, the order of Cf-H2O gasification reaction is in the range of 0.23~0.33; through on Arrhenius equation, the reaction activation energies have been obtained.
