Abstract

Acetaldehyde was removed using non-thermal plasma (NTP) combined with catalysis at ambient temperature under humid air conditions. Y zeolites with different SiO₂/Al₂O₃ molar ratios (5, 30, 80) loaded on 5 wt% Mn were prepared. Under the no humidity condition, the acetaldehyde removal capacity was related to the specific surface area of Y. In the presence of humidity, however, the conversion of acetaldehyde was high in Y zeolites with a high SiO₂/Al₂O₃ molar ratio having more hydrophobicity on the zeolite surface. The NTP system coupled with the hydrophobic zeolite catalyst was effective in acetaldehyde removal at room temperature in the presence of humidity.
