20110005938 | ELECTROLYSIS CELL FOR HYDROGEN CHLORIDE ELECTROLYSIS - Apparatus for hydrogen chloride electrolysis, comprising a cathode that has a layer of nitrogen-doped carbon nanotubes having functional groups containing nitrogen. | 01-13-2011 |
20130075249 | OXYGEN-CONSUMING ELECTRODE AND PROCESS FOR PRODUCTION THEREOF - An oxygen-consuming electrode is described, more particularly for use in chloralkali electrolysis, comprising a novel catalyst coating, as is an electrolysis apparatus. Also described is a production process for the oxygen-consuming electrode and the use thereof in chloralkali electrolysis or fuel cell technology. The oxygen-consuming electrode comprises at least an electrically conductive support, an electrical contact site and a gas diffusion layer comprising a catalytically active component, characterized in that the coating at least one fluorinated polymer, silver in the form of silver particles and silver oxide in the form of silver oxide particles, which is produced in a selected precipitation step. | 03-28-2013 |
20130078536 | GAS DIFFUSION ELECTRODES AND PROCESS FOR PRODUCTION THEREOF - A gas diffusion electrode is described, especially for use in chloralkali electrolysis, said gas diffusion electrode having finely divided components on the liquid side. The electrode is notable for a low perviosity to gases and a lower operating voltage. | 03-28-2013 |
20130087461 | CATALYST COATING AND PROCESS FOR PRODUCING IT - An improved catalyst coating comprising electrocatalytically active components based on ruthenium oxide and titanium oxide, especially for use in chloralkali electrolysis, is described. A production process for the catalyst coating and a novel electrode is also described. | 04-11-2013 |
20130144081 | PROCESS FOR THE PREPARATION OF ISOCYANATES - The invention relates to a process for the preparation of isocyanates in a system network comprising an isocyanate production plant, a chlorine production plant and a phosgene production plant, in which carbon dioxide formed as a by-product is partially to completely condensed out with the gaseous chlorine formed in the chlorine production plant and enters into the phosgene preparation process and, after the preparation of phosgene, the predominant part of the carbon dioxide formed is thereby sluiced out of the system network in gaseous form. | 06-06-2013 |
20130240370 | PROCESS FOR ELECTROLYSIS OF ALKALI METAL CHLORIDES WITH OXYGEN-CONSUMING ELECTRODES - Processes for electrolysis of alkali metal chlorides with oxygen-consuming electrodes having startup and shutdown conditions which prevent damage to the constituents of the electrolysis cell. | 09-19-2013 |
