摘要:

为了更高效地进行CO2的转化利用,许多学者开展了多种CO2转化方法的研究。介电阻挡放电(dielectric barrier discharge,DBD)能在低温常压的环境下还原CO2,是CO2转化利用的重要方法之一。为了设计出更好的DBD反应器、更佳的反应条件和催化剂,总结了近年来DBD转化CO2的相关研究。通过分析不同研究中过程参数、稀释性气体和催化剂等因素对CO2转化量和能量效率的影响,发现催化剂能大幅度提高DBD转化CO2的反应效率,并介绍了DBD中一些常用的催化剂。最后简要分析了此类研究的可能发展趋势。

Abstract:

In order to convert CO2 more efficiently, many scholars have carried out research on various CO2 conversion methods. Dielectric barrier discharge (DBD) is one of the important methods of CO2 conversion and utilization, it can reduce CO2 under the condition of low temperature and normal pressure. In order to design a better DBD reactor, reaction conditions and catalysts, this paper summarized the researches on CO2 conversion based on DBD in recent years. The effects of process parameters, diluting gases and catalysts on CO2 conversion and energy efficiency in different studies were analyzed. It was found that the catalyst can greatly improve the efficiency of CO2 conversion by DBD, and introduced some commonly used catalysts in DBD. Finally, the possible development trend of CO2 conversion by DBD was briefly analyzed.

Key words: dielectric barrier discharge (DBD), CO2 conversion, plasma, catalyst
