Abstract
The invention relates to a method for removing oxygen from a water containing reaction medium. A pair of electrodes (cathode and anode), are added to the medium, with a surfactant attached to the surface of at least one of the cathode and anode. The medium is kept at an acidic pH, and an electrical current is applied. Oxygen is drawn to the electrodes, displacing surfactant, and reacts with H+ ions and H2O molecules to form H2O2, which can then be removed.
Claims8
A method for removing oxygen from a water and crude oil containing reaction medium comprising placing a cathode and an anode into said reaction medium together with a surfactant, wherein said surfactant is adsorbed to at least one of said cathode and said anode, and applying an electrical potential created by said cathode and anode to said reaction medium, to attract molecular oxygen in said reaction medium to said cathode and atomic oxygen in said reaction medium to said anode with displacement of molecules of said surfactant into said reaction medium, and reacting said atomic oxygen with H+ ions and H2O to produce H2O2, at a temperature of from 200° C. to 240° C.
