%X K2O and K2SO4 are loaded on the catalyst V2O5(1%)/AC(V1/AC) by the method of wet immersing followed by drying.The effect of potassium compounds on the catalytic performance of V1/AC for the low temperature SCR of NO by NH3 was investigated.It was found that both K2O and K2SO4 as ultra-fine particles loaded in V1/AC can cause the catalyst deactivation.The adsorption of NH3 on the catalyst,especially the portion of weakly adsorbed NH3,is inhibited remarkably by the loading of potassium compounds.The inhibitio...
