Process and apparatus for purification of oxygen-containing gas

摘要: A process for purifying an oxygen-containing gas, characterized in that the comprises a first step of irradiating ultraviolet ray having short wavelength 110 nm or more and less than 200 to gas such as air be treated, thereby generate ozone, second medium 300 been treated step, form active oxygen, third long 380 convert above oxygen molecule ground state, wherein at least and/or steps are carried out presence photocatalyst preferably comprising orthorhombic titanium oxide particles said and, thereon, fine another metal; apparatus process. The can employed sterilizing, deodorizing instantaneously also decomposing organic compound which is difficult decompose by means conventional low molecular weight carbon dioxide water.
