The aim of Carbon2Chem® is to use CO2‐containing top gases from the steel production as a raw material for chemical products. The scientific foundations and tests with synthetic top gases on a laboratory scale have already been investigated. The technical implementation under real top gas conditions is tested in a technical center that was especially built for the project. In the demonstration plants which are directly connected to the integrated steelwork in Duisburg technologies for CO2 reduction are further developed.

Simultaneous hydrogenation of organosulfur compounds and O2 by Pd/Al2O3 catalyst was studied in a fixed bed reactor and by DRIFTS.

To remove H2S and HCN from acid gases, wet‐oxidative desulfurization such as the Takahax process can be applied. There, a continuous wastewater stream with high concentrations of ammonium thiosulfate and thiocyanate is discharged. By wet air oxidation of these salts at 473–573 K, fertilizer‐grade ammonium sulfate can be obtained. Thiosulfate wet air oxidation kinetics was investigated under industrially relevant conditions via the oxygen consumption rate in a high‐pressure reactor. Kinetic parameters were estimated with a dynamic reactor model. The experimental data was reproduced with a good average deviation of 2.17 %, and the applied reaction pathway is simple due to the high temperatures. This is an important step towards taylor‐made reactors for wet air oxidation of Takahax wastewater.
