Method for ozone oxidation reaction of VOC and / or gas phase inorganic reducing compound and method for producing ultrafine oxide particles used in the method

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating a large air quantity and low concentration volatile organic compound (VOC) using a phenomenon accelerating the oxidation reaction of ozone and the VOC on a transition metal-containing porous body when treating the VOC whose discharge regulation is increasingly reinforced based on Clean Air Act, treating malodor whose discharge regulation is increasingly reinforced based on a malodor prevention law and removing ethylene, an aldehyde and a terpene for preserving the freshness of farm products.SOLUTION: A method and an apparatus where ozone and a VOC (an alcohol, a ketone, an ester, an ether, an aromatic and the like) are brought into contact with a transition metal-containing porous body, the VOC is highly efficiently oxidized with ozone and then unreacted ozone is converted to harmless oxygen are proposed.
