%X Catalytic effects of Na,Ca,Fe and their composites on NO-char reaction in the presence of SO2 were investigated by Temperature Programmed Reaction(TPR) technique.The catalytic activity order of three metals is Fe>Ca>Na in the same conditions.SO2 may participate in the oxygen-transfer process to influence the metal catalytic effect in NO-char reaction.For three types of metal loaded catalysts,effects of SO2 concentration on their catalytic activities are different.The catalytic activity of Na loaded char is influenced most by the SO2 concentration.2% Na or Fe loaded chars and 3% Ca loaded char have the highest NO conversion activity in the presence of SO2.NaFe and Na-Ca composite catalysts have higher catalytic activity.Synergistic effect of Na-Ca and Na-Fe may be responsible for the high NO conversion activity of these bimetallic catalysts in the presence of SO2.
