博士 === 國立清華大學 === 化學工程學系 === 103 === Because of the progress of technique of engine,there are more and more exhaust gas ,like NOx and SO2,discharged into the atmosphere. According to existing commercial technologies are no perfect way to deal with this different harmful compounds.Our group have developed the promoted nitrogen oxides decomposition technology since several years age and we made great achievements theoretically and experimentally. The use of electro-catalytic technology developed ceramic supported electrochemical double cell can handle nitrogen oxides and sulfur oxides at the same time.This study show that we can take advantage of the anode supported electrochemical double cell to treat NOx and SO2 greatly. Then,we scale up the double cell into electro-catalytic honeycomb(ECH) and use ECH to treat the exhaust gas of boiler and diesel engine.The result of the experiment show that the reaction rate of ECH can reach several times of reaction rate of SCR.This result demonstrate the potential to be applied to the industry.
