| Abstract | 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/(RT)). 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/(RT)). NO reduction ratio is less than 02 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.
