Abstract

Gas effects on NO reduction by NH3 over sulfated CaO have been investigated in the presence of O2 at 700–850 °C. CO2 and SO2 have reversible negative effects on the catalytic activity of sulfated CaO. Although H2O alone has no obvious effect, it can depress the negative effects of CO2 and SO2. In the flue gas with CO2, SO2 and H2O co-existing, the sulfated CaO still catalyzed the NO reduction by NH3. The in situ DRTFTS of H2O adsorption over sulfated CaO indicated that H2O generated Brønsted acid sites at high temperature, suggesting that CO2 and SO2 competed for only the molecularly adsorbed NH3 over Lewis acid sites with NO, without influencing the ammonia ions adsorbed over Brønsted acid sites. Lewis acid sites shifting to Brønsted acid sites by H2O adsorption at high temperature may explain the depression of the negative effect on NO reduction by CO2 and SO2.
