PROBLEM TO BE SOLVED: To provide a method and device capable of cleaning harmful components in the harmful gas discharged from a reaction process using an organometallic compound as a reaction raw material and unnexessitating a post treatment without discharging any organic compound and a large amount of carbon dioxide after cleaning process. SOLUTION: The harmful gas is cleaned by brining the harmful gas into contact with the catalyst at 100-800 deg.C by using a cleaning device provided with a harmful gas introducing pipe, an oxygen or air introducing pipe, a cleaning cylinder which is connected to two introducing pipes and in which a catalyst carrying noble metal on an inorganic carrier and a catalyst carrying a catalyst consisting of metal oxides such as vanadium oxide, chromium oxide, manganese oxide, iron oxide, copper oxide and silver oxide or a catalyst carrying these metal oxides are packed, a means for heating the cleaning cylinder and a discharge pipe for the cleaned gas discharged from the cleaning cylinder. |
