The chambers are provided with an inlet opening and an outlet opening for the flowing electrolyte, each with one electrode. The inner space of the anode chamber and/or of the cathode chamber are/is subdivided by webs or ribs extending transversely with respect to the electrodes. The webs or ribs are provided at least regionally with holes or cut outs. The webs or ribs include at least one lower region free of holes or cut outs. The electrolysis device provides sufficient mixing in the upper foam phase in the longitudinal direction and also at the same time the airlift pump effect is maintained by way of ascending gas bubbles in the lower region.Type: ApplicationFiled: March 14, 2023Publication date: July 13, 2023Applicant: thyssenkrupp nucera AG & Co.

Publication number: 20220290319Abstract: Processes for alkaline electrolysis of water may involve pumping an electrolyte in a circuit between an anode half-cell and a cathode half-cell so as to keep the electrolyte concentration constant throughout the electrolysis process. One such process may involve supplying electrolyte from a first liquid reservoir to the anode half-cell and supplying an anolyte flowing out of the anode half-cell to an anodic gas separator, where gas is separated from the anolyte. The electrolyte may be supplied from a second liquid reservoir to the cathode half-cell and a catholyte flowing out of the cathode half-cell may be supplied to a cathodic gas separator, where gas is separated from the catholyte. Gas-stripped anolyte from the anodic gas separator may be returned to the second liquid reservoir and gas-stripped catholyte from the cathodic gas separator may be returned to the first liquid reservoir.Type: ApplicationFiled: August 19, 2020Publication date: September 15, 2022Applicant: THYSSENKRUPP UHDE CHLORINE ENGINEERS GMBHInventors: Jens Wilhelm KUHLMANN, Dirk HOORMANN, Joerg KOLBE, Lukas LUEKE, Gregor Damian POLCYN
