Papers by Keyword: NO_x Removal

Abstract: The conventional study of NO_x removal is mainly concentrated on the various chemical reactions, but takes no account of the important effect of temperature increase caused by the discharge. In this paper, we present a method whereby the reactive temperature in reaction region can be easily measured without affecting the discharge. By measuring the reactive temperature, it is revealed that the temperature in reaction region is closely related and linearly enhanced with the discharge power, and that the catalysis is not the main reason for the reactive temperature increase. By the investigation on the temperatures effect on the NO_x removal, it is found that the NO_x removal rate increases with the rise of temperature in reaction region. Therefore, the NO_x removal is tightly related with the temperature in reaction region that can be controlled by the discharge intensity under the various ambient temperatures.

Abstract: The photocatalytic effects of 4 samples, which TiO2 layer uniformly coated on Al fiber, are evaluated by NOx removal. An anatase TiO2 coating with good crystal quality and high Ti content exhibits the best photocatalytic effect on NOx removal. It is coincidence with the results of XRD, XPS results for 4 samples. The photocatalytic ability is enhanced by the introduction of H2O2 due to the formation of large amount OH radicals.
