Abstract The non‐thermal plasma (NTP) technique was shown to be a method to improve indoor air quality. In particular in kitchens, odorous emissions can be removed by NTP. A combined concept of adsorption of volatile organic compounds (VOC) and plasma regeneration of the adsorber was tested in adsorption‐regeneration‐adsorption cycles. As reference VOC, 2‐methylthiophene, 2‐methylpyrazine, 2‐acetylthiazole, nonanal and trans‐2‐nonenal were used in humid air streams. These odorous compounds are emitted during cooking and frying processes. The adsorption‐regeneration concept was also tested during a simulated frying process with garlic in rape oil. A hydrophobic zeolite was chosen as adsorber material and placed directly into the discharge zone of a plasma reactor.
