Chemical conversion of CO2

The "Dream Production" project, which is funded by the Federal Ministry of Education and Research is examining whether high-quality plastics – so-called polyurethanes – can be made on the basis of CO2 from power-plant flue gases.

For the project, the CO2 scrubber at the Coal Innovation Centre was retrofitted with a plant for cleaning and liquefying carbon dioxide. In this plant, the gas is filled into bottles, which are made available to the project partners so that they can investigate its usability for chemical synthesis.

Here, power plant CO2 is being used in a pilot system at Bayer Technology Services to make polyether polycarbonate polyols (PPP for short) which are then further processed by Bayer MaterialScience to make polyurethane plastics. Besides their use in building insulation, we find that light-weight components of polyurethanes in the automotive industry, say, make a contribution to lowering weight and, hence, help achieve significant energy savings. But polyurethanes are also a part of everyday life as material in high-quality mattresses and upholstered furniture.
