Publication number: 20240150262Abstract: Producing a product hydrocarbon includes subjecting a feed mixture containing a feed hydrocarbon and oxygen to selective oxidation to obtain a product mixture containing product hydrocarbon and water. A subsequent mixture is formed from a portion of the product mixture by separating a portion of the water. Oxygen in the feed mixture is partially converted during the selective oxidation, so that the product mixture has a first residual oxygen content and the subsequent mixture has a second residual oxygen content. Detection of the first and/or the second residual oxygen content is performed using a first measuring device. A second measuring device at the end of the catalyst bed detects temperature. Using a process control and/or evaluation unit, measurement data of the first and/or second measuring device(s) are detected and are evaluated and/or processed while obtaining follow-up data. Process control is carried out on the basis of the follow-up data.Type: ApplicationFiled: March 14, 2022Publication date: May 9, 2024Inventors: Mathieu Zellhuber, Martin Schubert, Andreas Meiswinkel, Anina Wohl
