AbstractThe non-thermal plasma is a very effective technique to decompose various kinds of gaseous organic compounds. The trichloroethylene (TCE) is one of the effective washing reagents to remove oily liquid materials or similar fatty materials from the solid surface but is harmful for human beings as the carcinogenic materials. The authors have been engaged in developing the non-thermal plasma technology to decompose that TCE efficiently. During the research on how to improve the decomposition efficiency of TCE, we found that the ozone generated in the air by the plasma can decompose TCE which is named as Indirect Process, comparing with the conventional plasma process named as Direct Process. We found that manganese oxide catalyst which can easily decompose the ozone and may generate oxygen radicals. The manganese oxide can improve the TCE decomposition efficiency, 20 or 80%, for Direct or Indirect Processes.

This paper mainly seeks to explore and answer some questions for desulfurization and denitration in thermal power plants in China. Firstly, the desulfurization and denitration technology applicated in the power plant in China at present were analyzed. It is considered that taken combination of the existed technique for purified the pollutants from the thermal power plants, not only lead to the wastage of huge amount of investment, increasing of operating costs, decreasing of the economic benefits, but also add an additional area. It is necessary to develop the integration technology of desulfurization and denitration simultaneously. Secondly the integration technology of desulfurization and denitration at present in China was briefly reviewed such as activated carbon adsorption, SNRB, etc. and most of those at a research stage include the plasma technology. In the third of the paper, the non-thermal plasma technology i.e electron-beam technique, corona discharge and dielectric barrier discharge were discussed. Finally, combined with the actual situation in China, the application prospects of the desulfurization and denitration technology using plasma discharge in the flue gas was bring up. The article also pointed out the barriers need to be overcome if the technology will be applied in power plant, as well as the development direction of desulfurization and denitration technology from flue gas in power plant in China.

Applications of non-thermal plasma in methane catalysis combustion have attracted a lot of attentions in recent years due to its outstanding and unique properties. We summarized two kinds of hybrid systems of plasma and catalysts for methane combustion reaction and compared these two figurations. Results prove that combining non-thermal plasma and catalysts has an excellent performance for methane total oxidation compared with single ones.
