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° 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.
A process for treating a gas containing reducing substances by hydrothermal electrolysis, comprising supplying an influent 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° C. or more but not more than the critical temperature of said aqueous medium and at a pressure that allows said aqueous medium to be kept in the liquid phase.
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 strong acid ion under application of a direct current at a temperature of 100° C. or more but not more than the critical temperature of said aqueous medium and at a pressure that allows said aqueous medium to be kept in the liquid phase.
An apparatus for treating a gas containing reducing substances by hydrothermal electrolysis, comprising a reactor having an inlet for introducing a gas containing reducing substances and an outlet for discharging the gas treated and capable of resisting the pressure of hydrothermal reaction, and a pair of electrodes for performing electrolysis in said reactor.
