26. Low Temperature Selective Catalytic Reduction of NO on CeO2-Fe3O4/TiO2,CeO2 /TiO2 Catalysts Prepared by Coprecipitation Method

Author

Zhen, Wen Long, Guo, Rui Tang, and Pan, Wei Guo

Abstract

CeO2-Fe3O4/TiO2 and CeO2/TiO2 catalysts were prepared by coprecipitation method, and their activities for selective catalytic reduction of NO with NH3 were investigated. As can be seen from the experimental results, the CeO2-Fe3O4/TiO2 catalyst prepared showed the best SCR activity and SO2 resistance. Based on the characterization results of BET, XRD, NH3-TPD and XPS the excellent performance of CeO2-Fe3O4/TiO2 catalyst should be resulted from its large surface area, high NH3 adsorption capacity and high concentration of surface chemisorbed oxygen.

Abstract

The catalysts of Mn/TiO2, Fe/TiO2 and Mn-Fe/TiO2 prepared by coprecipitation method were investigated for low temperature selective catalytic reduction of NO with NH3. The catalytic activity and SO2 resistance of these three catalysts were tested and the properties of the catalysts were characterized by using N2-BET, XRD, H2-TPR, NH3-TPD methods. It was found that the doping of iron reduced the catalytic activity of Mn/TiO2 catalyst at low temperature and also has an adverse effect for its SO2 resistance at the same time. The decrease of surface area , redox ability and surface acid sites caused by doping of iron might be the main reasons for poor performance of this catalyst.

28. The Emission Control Technology of PM2.5 from Coal-Fired Plant

Author

Pan, Wei Guo, Shi, Chao Lin, Li, Fu Xiao, Luo, Han Cheng, Guo, Rui Tang, Ding, Hong Lei, and Hong, Jie Nan

Abstract

A major source of PM2.5 is the combustion of coal-fired power plant, so its very necessary to monitor and control the emission of PM2.5 form power plant. This paper summarizes the main emission control technologies of PM2.5 for coal-fired plant. As the traditional electrostatic precipitators has low removal efficiency of submicron particles, so we improved the supply conditions of the precipitator, and pre-charged to improve the particle properties. Through this article, we know that using electric coagulation technology to control the particles form plant is practicable, and it has a good prospect for development.
