Electrochemical cell arrangement for the production of hydrogen peroxide
Abstract:
Methods and apparatus are provided for the generation of hydrogen peroxide from an electrochemical (EC) cell arrangement. One embodiment of the apparatus comprises an EC cell having anode and cathode electrodes with a cation exchange membrane disposed between them to form anode and cathode compartments. An aqueous salt solution is supplied to the anode compartment and water and oxygen are supplied to the cathode compartment. An electric potential applied across the anode and cathode electrodes initiates an electrochemical process that results in the formation of an acid anolyte solution in the anode compartment and an alkaline catholyte solution in the cathode compartment. The anolyte solution and the catholyte solution are combined in a neutralizing chamber to form a neutral aqueous solution comprising hydrogen peroxide, salt, and water. The hydrogen peroxide is separated from the neutral aqueous solution by conventional means.
