Document Type and Number:
Japanese Patent JP4332107
Kind Code:
B2
Abstract:
To provide a method for irradiating ultra-violet rays a water retention member added with water droplets, generating OH radical in the water droplets and modifying ethylene gas into ethane and water through the OH radical. ?>Water is supplied to the aeration water retention member 2a formed with a water retention surface capable of holding water in its particle shape in such a way that the water is held on it under particle shape to cause the water retention surface to be kept in a state where the water retention surface is wetted with water droplets. Then, ultra-violet rays S with a wavelength of 254 nm are irradiated water held on the water retention surface from a near distance within 10 mm while controlling a location near the ultra-violet rays emitting tube 3 to a temperature range of about 10 DEG C to 40 DEG C and then the OH radicals R are generated in the water droplets M with energy of irradiated ultra-violet rays. Further, gas containing ethylene gas is aerated the water retention surface holding water containing the OH radicals and the ethylene gas E contacted under an action of the OH radicals is modified into ethane (e) and water (w).
