Abstract

Abstract: The non-thermal plasma regeneration method, which has great exploring space and application prospect, is a kind of new method for the regeneration of adsorbents.In this paper, the non-thermal plasma regeneration method are compared with traditional regeneration methods, and the advantages and disadvantages of these methods are listed.The concepts of plasma, the producing mode of non-thermal plasma and the mechanism of this method are also described in this paper.Furthermore, the research progress of this method both at home and abroad are introduced in detail.At last, the characteristics of this method are summarized and the problems to be settled urgently are put forward.Analyses show that this method, compared with the traditional regeneration methods including temperature swing adsorption and pressure swing adsorption, has the advantages of low reaction temperature, speediness and high efficiency.However, the method is still in the stage of laboratory research, many theories and engineering problems still remain to be resolved.

Key words: non-thermal plasma, regeneration, adsorption, desorption, adsorbents
