A hydrothermal electrolytic apparatus comprises a reaction cell for electrolyzing influent at high temperature and high pressure, wherein an overall surface area of a pair of electrodes located in the reaction cell per 1 mof the volume of the influent is 0.05 mor more. The hydrothermal electrolytic apparatus has two or more tubular reaction cells each having a metal inner wall serving as a cathode, and an anode is provided in each of the reaction cells. A hydrothermal electrolytic process comprises incorporating conductive particles into an influent to substantially increase a surface area of electrodes during hydrothermal electrolysis.

Apparatus and method for hydrothermal electrolysis

An object of the present invention is to provide a process and an apparatus for treating a gas containing reducing substances to efficiently degrade and remove the reducing substances. As a means to achieve this object, the present invention provides a process for treating a gas containing reducing substances by hydrothermal electrolysis, comprising supplying a gas containing reducing substances into a reactor charged with an aqueous medium containing a halide ion under application of a direct current at a temperature of 100&deg; C. or more but the critical temperature of said aqueous medium or less and at a pressure that allows said aqueous medium to be kept in the liquid phase.

Method and apparatus for treatment of gas by hydrothermal electrolysis

An object of the present invention is to provide a process and an apparatus for treating an aqueous medium at low running costs with a decreased electricity required for hydrothermal electrolytic reaction. The present invention proposes a two-step process comprising a first step of performing a conventional hydrothermal reaction or a conventional electrolytic reaction prior to hydrothermal electrolytic reaction to degrade readily degradable substances or ammonia or various electrolytically degradable organics and then a second step of performing hydrothermal electrolytic reaction to degrade the remaining organics, whereby the electricity consumed by hydrothermal electrolytic reaction in the second step can be greatly reduced.
