PROCESS FOR THE ELECTROLYTIC SEPARATION OF OXYGEN FROM ITS MIXTURES AND EQUIPMENT FOR IMPLEMENTING SUCH PROCESS

摘要

he process comprises the following steps: a) bringing into contact an oxygen containing gas with a gas diffusion cathode which does not contain a hydrogen peroxyde decomposition catalyst, b) providing a potential difference between the cathode and an anode, so that the oxygen is converted to peroxyde at the cathode, the peroxyde is diffused through an aqueous electrolyte up to the anode, and the peroxyde is converted to pure oxygen at the anode, the process is a new method capable of separating the oxygen through a bi-electronic process. The equipment comprises a single compartment electrolytic cell (1) with at least one cathode (8) and one anode (9), an inlet (12) through the cathode for the introduction of a gas mixture which contains oxygen and an outlet (5) for pure oxygen produced in the cell.
