Trimethylamine (TMA) is a product of decomposition of plants and animals. With its strong fishy odor in low concentrations, TMA is the main agent for the odor often associated with fouling fish, some infections, and bad breath. This study focused on the adsorption of TMA over various nanoporous zeolites for application in the lowtemperature deodorization of fishy odor from raw fish oil. The faujasite (FAU, Si/Al=3), mordenite (MOR, Si/Al=10), and ZSM-5 (MFI, Si/Al=25-335) zeolites were employed. The TMA was adsorbed in a batch type reactor at 50 oC. The FAU zeolite exhibited the high adsorption ability, which, in combination with its wide surface area and pore volume, may have induced the high adsorption ability. Despite having a small surface area of size similar to that of the HMFI zeolite, the H-MOR(10) zeolite exhibited a large TMA adsorption. The H-MOR(10) zeolite has stronger acid sites than those of the other zeolites, and this increased strength was considered to have generated more attractive adsorption with TMA ions, because TMA interacts briskly with cations of acid sites on the zeolites. Approximately 60% of the odor of the raw fish oil was removed by adsorption on the H-FAU(3) zeolite at 50 oC.
