Abstract

Abstract: A non-thermal plasma (NTP) discharge is used in this study for the activation and regeneration of MS-13X pellets packed in a MS-13X & glass beads packed bed dielectric barrier discharge (DBD) reactor. NTP activation ( in-situ ) of MS-13X efficiently removes the adsorbed carbonaceous compounds and moisture resulting in an improved VOC adsorption. In addition, NTP exposure is used for the regeneration of the used MS-13X for cycled storage and discharge (CSD) removal of VOC from air. The amount of adsorbed toluene, products formed and the surface and bulk properties of the regenerated used MS-13X shows complete regeneration of used MS-13X. Finally, the stability of MS-13X during 10 cycles of CSD shows no degradation in performance. Thus, NTP exposure is proven to be successful for both the activation and regeneration of MS-13X pellets used for cyclic CSD process. Graphical abstract: Image 1
