Our flagship project Steel2Chemicals focuses on the development of a closed value chain in which CO from residual gases from steel production is used as raw material in the chemical industry.
- Chemical industry needs CO as a feedstock
- Steel industry needs a solution to reduce their emissions
- Connecting them creates a a circular value chain and thus reduces CO2 emission
- Steel2Chemicals focuses on demonstrating the technical and economic feasibility of this value chain
Chemical industry needs alternatives for fossil resources
The chemical industry is looking for alternatives for fossil resources. This requires innovative technologies that can be used on an industrial scale, are economically feasible and can be integrated in a circular value chain. The steel industry in its turn is a major contributor to global CO2 emissions with between 1.7 and 2.5 tons of CO2 emitted per ton of steel produced. For this sector, a circular value chain offers a solution to reduce emissions.
Steel2Chemicals: a circular carbon chain
By using carbon from residual gases from steel production as feedstock for the chemical industry, the carbon is stored in a chemical product and not emitted as CO2. The raw materials in these new products can – at the end of their lifecycle – be used as a source of carbon in the steelmaking process.
Where CCS offers just a short-term solution, this concept of circular carbon will reduce the demand for fossil-based material and offer a real alternative for linear value chains.
Together with partners ArcelorMittal, Tata Steel, DOW, Ghent University and TNO, we explore the possibility of using carbon monoxide from blast furnaces for the synthesis of naphtha. This ‘synthetic’ naphtha can (partly) replace the demand for fossil naphtha used to produce e.g. ethylene, a major chemical building block and starting materials for plastics.
This is not about a little bit of CO2, it’s about millions of tons of CO2Matthijs Ruitenbeek – DOW
The challenges of converting steel gases into synthetic naphtha
In realizing this new technology to close the carbon circle, the partners in the Steel2Chemicals project are dealing with challenging issues:
- How to separate CO from CO2, N2 and other impurities?
- How to demonstrate the catalyst is suitable to convert CO to naphtha in an industrial environment?
- Which conditions make this symbiosis of steel and chemical industries technically and economically feasible?
- How to demonstrate the robustness and replication potential of this new route?
