<p>PURPOSE:To oxidize and decompose a malodorous gas contg. an org. reducing gas such as gaseous acetaldehyde and formaldehyde and to make the gas harmless. CONSTITUTION:A gas contg. reducing gases is brought into contact with an gas-passable metallic porous body 2 impregnated with aq. hydrogen peroxide 3 to oxidize the reducing gases. Besides, the porous body 2 is filled in a gas passage in a reaction vessel 1, and the aq. hydrogen peroxide 3 is intermittently or continuously supplied.</p> |
