Abstract

To realize integrated removal of multiple pollutants and shorten the flue gas purification process and reduce the overall system resistance

the X-ray photoelectron spectroscopy(XPS) characterization and specific surface area and pore size distribution analysis were performed to study the role of the physical and chemical properties of the ceramic catalytic filter in the pollutants removal and the mechanism of the internal pollutant removal. Moreover

an experimental setup for integrated removal of multiple pollutants was built up

and experiments were conducted to study factors affecting the denitrification and dust removal performance of the ceramic catalytic filter tube integrated removal system. The results show that

injecting ammonia gas in front of the integrated removal tower can realize the integrated and efficient removal of dust and NO_x. The mass concentration of dust at outlet of the ceramic catalytic filter is less than 5 mg/m~3

and that of NO_x at the outlet is less than 50 mg/m~3.
