20090178931 | Electrolysis Cell for Hydrogen Peroxide Production and Method of Use - An electrolytic cell for the production of hydrogen peroxide with faradic efficiency and a method for the production of highly pure hydrogen peroxide with high faradic efficiency are disclosed. The cell is provided with a separator of high hydraulic permeability and is equipped with an oxygen-fed gas-diffusion cathode and with an anode activated with a catalyst for oxygen evolution. The high faradic efficiency of hydrogen peroxide generation is allowed by the dilution of product hydrogen peroxide by the anolyte crossing the permeable separator, and by keeping the operating temperature at values below 50° C. | 07-16-2009 |
20090200162 | Anode for Electrolysis - The invention relates to an anode comprising a titanium alloy substrate coated with noble metals by thermal decomposition of precursors thereof. The alloy of the substrate includes elements which can be oxidised during the thermal decomposition step, allowing electrical energy savings and a prolonged duration in industrial electrolytic processes. The anode of the invention is suitable for chlor-alkali electrolysis, allowing to produce chlorine with a lower oxygen content and a lower energy consumption than the anodes of the prior art. | 08-13-2009 |
20100272830 | Biocide Combination for use in Agricultural Applications - The invention is directed to a combination characterised by a high biocide power for use in agricultural applications, comprising a sodium or potassium hypochlorite solution and an agent allowing to generate hypochiorous acid at the moment of the application, adjusting the concentration thereof in a simple way. | 10-28-2010 |
20140246306 | ANODIC COMPARTMENT FOR METAL ELECTROWINNING CELLS - The present invention concerns an anodic compartment for metal electrowinning cells delimited by a frame-shaped skeleton comprising an envelope including a permeable separator secured to said frame-shaped skeleton by means of a frame-shaped flange, at least one anode obtained starting from a valve metal substrate coated with at least one corrosion-resistant catalytic layer, said anode being inserted inside said envelope, and a demister located above said anode and delimited by said separator and said skeleton. The invention also concerns an electrochemical cell for metal electrowinning comprising at least one such anodic compartment. | 09-04-2014 |
20150014181 | METHOD AND APPARATUS FOR TREATMENT OF EFFLUENTS FROM PRODUCTION PLANTS OF EPOXY COMPOUNDS - The invention relates to a process of abatement of the organic content of a depleted brine coming from epoxy compound production involving a vapour stripping step and a mineralisation with hypochlorite in two steps, at distinct pH and temperature conditions. | 01-15-2015 |
20150041323 | CELL FOR DEPOLARISED ELECTRODIALYSIS OF SALT SOLUTIONS - The invention relates to a salt solution electrodialysis cell for production of the relevant acids and bases by means of a process with reduced or nil consumption of electrical energy. The cell comprises an anodic chamber fed with hydrogen and a cathodic chamber fed with oxygen or air, provided with the relevant gas-diffusion electrodes; the driving power of the electrodialysis process is given by the oxidation and reduction chemical potentials of hydrogen and oxygen fed to the two chambers. | 02-12-2015 |
20160068982 | ELECTROLYTIC CELL FOR METAL ELECTROWINNING - The invention relates to a cell for metal electrowinning equipped with a device useful for preventing the adverse effects of dendrite growth on the cathodic deposit. The cell comprises a porous conductive screen, positioned between the anode and the cathode, capable of stopping the growth of dendrites and preventing them from reaching the anode surface. | 03-10-2016 |
