Method and Device for Producing Oxidation Products

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and system for efficiently producing basic chemical raw materials—such as methanol, ammonia, alcohols, or carboxylic acids—starting from carbon dioxide (CO2) and water (H2O). The process uses a high-temperature electrolytic cell to generate syngas (a mixture of hydrogen and carbon monoxide) and oxygen. The syngas is then converted into intermediates, which are further oxidized using the generated oxygen to produce the target substances. The system allows precise control over the produced gas ratios and streamlines the integration of all steps, improving overall process efficiency.

Patent Abstract

It is the object of the invention to efficiently produce raw materials. To solve this object, a method for producing a raw material comprises the following steps: - Supply of CO and H2O into the cathode chamber of an electrolysis device and generation of a synthesis gas by applying a direct voltage to the anode located in the anode chamber and the cathode located in the cathode chamber of the electrolysis device, wherein the anode chamber is separated from the cathode chamber by a wall permeable to oxygen ions; - Further processing of the synthesis gas produced by electrolysis into an intermediate product; - Production of the raw material by oxidation of the intermediate product with the oxygen produced by the electrolysis. The invention furthermore relates to a device for carrying out the method.
