介质阻挡放电等离子体催化反应器研究进展及应用展望

Due to ever-increasing energy crisis and environmental issues, the development of efficient and environmentally friendly catalytic technologies becomes a major research area. Plasma (containing highly energetic species) has shown significant potential in fields of catalysis and environmental protection. This review provided a comprehensive analysis of the state-of-the-arts on dielectric barrier discharge (DBD) plasma catalytic reactors, especially their contributions to process intensification of catalytic reactions with advantages such as reducing reaction activation energy and creating new reaction pathways. Based on the critical comparative review of different cases of conventional DBD reactors, coupled plasma-structured catalyst reactors, coupled plasma-separation reactors, coupled plasma-fluidized bed reactors and other new reactor designs, the uniqueness of different DBD systems was identified. In detail, structured catalysts significantly improved mass and heat transfer, separation-coupled reactors achieved efficient product separation and fluidized beds exhibited excellent processing capability for specific reactions. Additionally, relevant challenges existing in the field and possible future research directions were discussed and proposed for progressing the plasma technology for practical adoptions in the future.
