Abstract
Non-thermal plasmas are innovative and promising tools with respect to end-of-pipe treatment of waste gases. Among other features, they allow decomposition of low concentrations of volatile organic compounds in air streams at atmospheric pressure. In this paper, a plasma-catalytic hybrid system for the removal of trichloroethylene (TCE) in dry air is discussed. A pin-to-mesh electrode concept is used to obtain a positive corona discharge. A packed bed of TiO2 photocatalyst partially fills the gap between the pin(s) and the mesh. TCE destruction performances of the system with and without the photocatalyst are compared. It is shown that the presence of the catalyst enhances the TCE decomposition with a maximum removal fraction of 85% at an energy density of 600 J/l for a total air flow rate of 1.5 slm with 100 ppm TCE at the inlet.
