A method for producing a target compound includes distributing a feed mixture containing ethane to multiple reaction tubes of a shell-and-tube reactor arranged in parallel, and subjecting to an oxidative catalytic conversion of the ethane in the reaction tubes. The catalytic reaction is carried out by means of catalysis zones with different activity arranged in series in the reaction tubes. One or more catalytically active materials and one or more catalytically inactive materials are provided in each of the catalysis zones. The different activity of the catalysis zones is effected by providing the one or more catalytically active materials having identical or essentially identical basic formulation, wherein the one or more catalytically active materials is or are prepared using different calcination intensities.

Process and system for preparing a target compound

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.
