Launching the technical center

The Carbon2Chem® research project is pursuing the goal of utilizing the CO2 contained in the gases released during steel production as a raw material for base chemicals. The first step is to clean the metallurgical gas.

Das Technikum startet
Integrated steel mill

The gases from the coking plant, blast furnace, and converter contain up to 400 different components, some of which are valuable. The location of the technical center in Duisburg was deliberately chosen so that all three gases can be processed.

Measuring station

The measuring station is where all information of the individual plants of the technical center comes together. Here, the functions and analysis results are checked, and the processes are controlled and monitored around the clock.

Water electrolysis

With the help of water electrolysis, additional hydrogen is generated, which is converted into chemical products in the laboratory together with the purified steel mill gases.The electricity for this process is generated from renewable energy. During the electrolysis process, water is split into hydrogen and oxygen at the electrodes.

Gas scrubbing

The gases compacted with the aid of a compressor are cleaned in two separate processes at the core of the technical center: by adsorption and absorption.


After gas scrubbing, the pure chemical elements H2, CO, CO2, and N2 are fed into the laboratory and turned into ammonia/urea, methanol, and oxymethylene ether. These resources are used to produce important daily products.

Final products

The chemical products gained through Carbon2Chem are key ingredients in the production of items in strong demand across the globe.

- Fertilizers
- Plastics
- Fuels


This task is completed by Linde. A pressure swing adsorption process is used to extract hydrogen from coke plant waste gases and process it to the highest purity. This is used in the technology center for the production of resources.


This is the task of thyssenkrupp Industrial Solutions. The washing process removes undesired substances from blast furnace and converter gases. The remaining CO2 is then turned into usable resources in the laboratory.
