Title:
APPARATUS AND METHOD FOR HYDROTHERMAL ELECTROLYSIS
Document Type and Number:
WIPO Patent Application WO/2000/047520
Kind Code:
A1
Abstract:
A hydrothermal electrolysis apparatus characterized in that it is equipped with a reaction chamber for electrolyzing a material to be treated under a high pressure at a high temperature and the total surface area of a pair of electrodes disposed in the reaction chamber (31) is 0.05 m?2¿ or more per m?3¿ of the volume of the material to be treated; a hydrothermal electrolysis apparatus characterized in that it has two or more of cylindrical reaction chambers, each having an inner metal wall acting as a cathode, and anodes are disposed within the reaction chamber; and a hydrothermal electrolysis method characterized as comprising incorporating conducting particles into the material to be treated, to thereby substantially increase the surface area of electrodes in hydrothermal electrolysis are disclosed as some embodiments of the present invention. Such apparatuses and methods for hydrothermal electrolysis can be used for treating a large amount of liquid wastes with good efficiency.
