제목 Removal of ethylene from air stream by adsorption and plasma-catalytic oxidation using zeolite-supported palladium catalyst
초록 Volatile Organic Compounds (VOCs) can be harmful for the environment and human health. Among the many VOCs, ethylene is one of them that is produced by agricultural commodities that cause the ripening of fruits and vegetables. Controlling the ethylene activity can lead to extend the postharvest shelf life of fruits and vegetables. The adsorption of dilute ethylene was performed in corona discharge-coupled catalytic reactor(CDCCR) with palladium-coated zeolite pellets serving as both adsorbent and catalyst. The removal of ethylene in this system was carried out by cyclic operation consisting repetitive steps: 1) adsorption followed by 2) plasma-catalytic oxidation. Ethylene was removed from air stream with concentration of 20ppm and enriched on zeolite surface during adsorption process for 60 min followed by application of plasma to recover the adsorption capability of the surface.
