摘要
After study of how Calcium-based sorbent (CaCO3) and soild materials (CaSO4 and Ash) influence the conversioin of ammonia to NO and N2O in a fixed bed reactor, the following important conclusions are obtained: (l) the catalytic effects of CaCO3, CaSO4 and Ash on ammonia to NO and N2O are CaSO4 >CaCO3 >Ash; (2) Below temperature of 1100 K, calcium-based sorbent and solid materials have some catalytic effects on ammonia to NO and N2O, when the temperature is increased above 1100 K, catalytic destruction of NOx. and N2O with CaCO3 and ash is stronger than catalytic formation. So it makes the emission of NO. and N2O low, (3) whether in high or low temperature, CaSO4 has strongcatalytic formation of NOx. and N2O.
