Abstract
A method for producing hydrogen peroxide by electrical discharge in a material gas in which oxygen concentration is not less than 0.5% and less than 13% is disclosed in the first aspect. In the second aspect, an apparatus for producing hydrogen peroxide having a plurality of electrical discharge chambers connected in series is disclosed. In the third aspect, an apparatus in which a material gas is recycled is disclosed. In the forth aspect, an apparatus having its electrodes covered with dielectric and an electrical discharge chamber which is cooled by a cooling member. In the fifth aspect, a method for producing hydrogen peroxide having a step of inactivating radical species produced by electrical discharges is disclosed. In the sixth aspect, an apparatus having a condensation tube coated with resin with low reactivity with hydrogen peroxide is disclosed. In the seventh aspect, an apparatus for, after producing hydrogen peroxide, mixing the exhaust gas and the air in order to remove danger of explosion is disclosed. A method and an apparatus for producing hydrogen peroxide in accordance with the present invention produces hydrogen peroxide safely and efficiently.
