- Abstract
Pulsed dielectric barrier discharge (DBD) combined to palladium supported on alumina beads were investigated for propene removal from air. Effects of thermal-catalysis, plasma-catalysis (in-plasma catalysis and postplasma catalysis), and plasma-alone on the propene removal were compared. Results are presented in terms of C3H6 removal efficiency, energy consumption, and by-products production. Temperature dependence studies (20-250 °C) show that in all conditions of input plasma energy density explored (23-148 J L-1) the plasma-catalysis systems exhibit better propene conversion efficiencies than thermal catalysis at low temperature (60% at 20°C). Plasma-alone treatment has a similar effectiveness to plasma-catalysis at room temperature but leads to the formation of high by-products concentrations. It appears that in plasma-catalyst system, C3H6 removal strongly increased whatever the configuration used and was helpful to minimize by-products formation.
