| 摘 要： | 通过对中国一种贫煤焦还原N0的实验，确定不同条件下该反应的动力学参数及催化剂对这些参数的影响。结果表明，在贫氧条件下(a＜1)，催化剂对贫煤焦还原N0具有重要的催化作用，可降低贫煤焦与N0还原反应的活化能，增大频率因子，从而提高反应速率和N0的还原率。

Effects of Catalysts on Kinetic Parameters of NO Reduction by the Lean Coal Char |
| |
| Abstract: | This paper has established kinetic parameters of a reaction of NO reduction by a Chinese lean coal char in different conditions and studied effects of catalysts on the parameters via experiments.Experimental results show that catalysts have important catalysis to NO reduction by lean coal chars.Catalysts can decrease the active energy,increase frequent factor of the reaction of NO with lean coal char,enhance the reaction rate and improve the efficiency of NO reduction at stoichiometric ratio less than 1. |
