K/Co-Mg-Mn-Al mixed oxide catalyst system for direct NO decomposition
Original language description
In this study, the effect of Mg partly substituting Co in the Co4MnAlOx mixed oxide catalyst subsequently modified by different potassium amount, maintaining (CoxMgy)/Mn/Al molar ratio constant, was studied. The prepared catalysts were characterized by XRD, BET, TPR-H2, TPD-CO2 and tested for direct NO decomposition in inert gas and in the presence of oxygen. Presence of magnesium and potassium in the Co4MnAlOx mixed oxide led to the significant increase in catalytic activity for decomposition of NO. Surprisingly, no direct correlation between NO conversion and magnesium content was observed. However, Mg in the catalysts affected stability of K at reaction temperatures positively. DeNO activity depended on the K amount. When the catalyst contained optimum amount of 1 - 2 wt. % K (Fig. 1), maximum NO conversion was achieved.
