Activities of IEK-1 in the BMWK funded project MemKoWI

Our objective within the project „MemKoWI“ is to make membrane technology ready for larger-scale applications in an industrial context. More specifically, we will develop ceramic membranes for the separation of carbon dioxide (CO2) and hydrogen (H2) on-site from industrial gas flows, such as flue gas from cement production and furnace gas in the steel industry. These will be assembled in specially designed stainless-steel housings that accommodate a larger membrane area.

The separation of CO2 is usually only achievable on the basis of affinity differences (adsorption) with the membrane material, which can be achieved by applying a hybrid carbon-silica material, or possibly a microporous carbon. For the separation of H2, the membrane should work as a molecular sieve, which means have a pore/channel diameter of 0.3-0.4 nm, comparable to the size of the gas molecule. The proposed solution to achieve this involves the production of a reduced graphene-based membrane, which has a similar stacked laminate structure of carbon layers as natural graphite. In addition, also other carbon structures will be studied. The project, coordinated by herion, is being carried out with various industrial partners.
