Removal of Hexanal by Non-thermal Plasma and MnOx/γ-Al2O3 Combination

doi:10.1016/S1872-2067(11)60391-4

Abstract

Abstract: The removal of hexanal by a combination of a non-thermal plasma and catalyst was studied. There was a synergism between the plasma and γ-Al₂O₃ that gave a hexanal removal efficiency of 87.1% at 80 °C and 2.8 W discharge power. The removal efficiency was improved to 96.5% when the γ-Al₂O₃ was loaded with 7.5% MnO_x, and a comparable efficiency was also obtained with a Pt/γ-Al₂O₃ catalyst. The 7.5%MnO_x/γ-Al₂O₃ catalyst was stable over 50 h use during which the removal efficiency did not decline.

Key words: cooking oil fume, hexanal, γ-aluminum oxide, non-thermal plasma, synergistic effect
