Abstract
A device is disclosed for the generation of hydrogen peroxide. The device produces hydrogen peroxide on an as-needed basis through the use of electrolysis of water, wherein the hydrogen and oxygen are mixed in the electrolyzer, and the hydrogen and oxygen mixture in water are reacted in a reactor to produce hydrogen peroxide.
Claims2
An apparatus for the production of hydrogen peroxide in situ, comprising:
- a housing having a water inlet port for admitting water and a hydrogen peroxide outlet port;
- an electrolyzer disposed within the housing and in fluid communication with the water inlet port for generating hydrogen and oxygen wherein the electrolyzer comprises a plurality of electrodes separated by electrically non-conductive spacers, wherein the spacers form channels along the length of the electrodes and wherein the spacers separate the electrodes to form a gap between about 100 micrometers and about 450 micrometers;
- and
- a reactor for producing hydrogen peroxide disposed within the housing and between the electrolyzer and the outlet port, wherein water flows in the water inlet port, through the electrolyzer to the reactor and out the outlet port;
- wherein the electrodes are substantially a sheet of material having localized peaks.
