分别以Na2 CO3和十二烷基苯磺酸钠（ LAS）为催化剂，利用常压热分析天平对福建省建欣和创宏两种无烟煤进行了水蒸气气化动力学实验。在850～950℃测定了催化剂加载量为0～15％（质量分数）时转化率随气化反应时间的变化。进而采用缩核模型对实验数据拟合，给出相应的动力学参数，实验结果表明，Na2 CO3和LAS催化剂对提高气化速率及降低反应活化能具有明显作用。由于LAS催化剂的加载过程可使钠离子实现更充分和均匀的分散，即使在很小的Na＋基准浓度状态下，也可实现催化气化的高效转化与缩短气化反应时间的目的，这为LAS催化剂的应用与开发提供了新的方向。

With sodium carbonate and sodium dodecyl benzene sulfonate used as the catalysts respectively, the steam gasification kinetic experiments of Fujian Jianxin and Chuanghong anthracites were conducted in an atmospheric thermal balance, and the effects of catalyst loading amount ( 0% ~15%) and gasification temperature ( 850 ~950 ℃) were examined.The experimental data were fitted by shrinking core model. Meanwhile, the kinetic parameters were obtained.The results show that both sodium carbonate and sodium dodecyl benzene sulfonate can significanlt y increase the gasification rate and er duce the activation energy of gasification reaction of the two anthracite samples.Because the loading process of ac talyst LAS can make the sodium ions being dispesr ed more evenly, even with low concentration of Na+, the carbon conversion can be imp roved significantly and the gasificationr eaction time is reduced to .The experime nts prove that it is a new way for the application and devle opment of LAS in catalytic ts eam gasificationo f Fujian anthar cti e.
