在流化床中考察了煤矸石开孔空心球对CO还原NO的催化效果，并对CO催化还原NO的动力学进行了评价。在773-923 K下，无水蒸气存在时，反应速率常数为k= 5210 exp-113600/（R T）。在反应初始阶段（< 1 s）和T> 873 K，NO还原率随反应停留时间的增加而迅速增加;当CO与NO初始浓度比小于4时，提高反应温度可获得较高的NO还原率。有水存在时，煤矸石空心球对NO还原的催化作用减弱，反应速率常数k= 0.31 exp− 60750/（RT）。在T≤ 923 K时，当CO与NO的初始浓度比为4时，反应停留时间为2.5 s时，NO还原率小于0.2;在T≤ 923 K时，CO与NO的初始浓度比对NO还原率的影响很小。
The catalytic effect of coal gangue hollow ball with open pores on NO reduction by CO in fluidized bed was investigated, and the kinetics for the catalytic reduction of NO using CO was evaluated. In the absence of water vapor at 773–923 K, the reaction rate constant was k= 5210 exp− 113600/(R T). NO reduction ratio rapidly increased with reaction residence time at initial stage (< 1 s) and T> 873 K; high NO reduction ratio was achieved by increasing reaction temperature when the initial concentration ratio of CO to NO was less than 4. In the presence of water, the catalytic effect of coal gangue hollow ball on NO reduction was weakened, and the reaction rate constant was k= 0.31 exp− 60750/(R T). NO reduction ratio is less than 0.2 when reaction residence time was 2.5 s at T≤ 923 K when the initial concentration ratio of CO to NO was 4, and the initial concentration ratio of CO to NO had negligible effect on NO reduction ratio at T≤ 923 K.
