Patent number: 6533999Abstract: Ozone generated from an ozonizer is added to a polluted gas containing harmful substances, which is generated from a polluted gas source. Then, the ozone-added polluted gas is allowed to flow through an adsorbing layer containing a high-silica adsorbent that adsorbs both ozone and harmful substances. The harmful substances contained in the polluted gas are converted into harmless substances within the adsorbing layer by the action of the ozone.Type: GrantFiled: April 1, 1999Date of Patent: March 18, 2003Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Jun Izumi, Akinori Yasutake, Nariyuki Tomonaga, Hiroyuki Tsutaya

Patent number: 6503469Abstract: A polluted fluid, such as exhaust gas from a refuse incinerator, containing at least one pollutant, such as volatile organic compounds (VOCs), SOx or NOx, is processed by passing the polluted fluid through an adsorbing layer containing a high-silica adsorbent capable of adsorbing both ozone and at least one pollutant to adsorb at least one pollutant on the adsorbent. Then, ozone is brought into contact with the adsorbing layer to oxidize and decompose the pollutant adsorbed on the adsorbent, while stopping the flow of the polluted fluid.Type: GrantFiled: June 22, 1999Date of Patent: January 7, 2003Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Jun Izumi, Akinori Yasutake, Nariyuki Tomonaga, Hiroyuki Tsutaya
