Focus/Key Topic:


Gas separation membranes are a more sustainable alternative to existing processes in many areas. They are already used to separate nitrogen from air, CO2 from natural gas or hydrogen from refinery gases. In order to increase the performance of the membrane processes and to expand the field of application, great efforts have been made in recent years in the development of new membrane materials. However, the newly developed materials have always been too costly and/or production has not been highly scalable to industrial standards.

To solve this problem, we are working with our project partners on the production of novel gas permeation membranes using plasma-enhanced gas phase deposition. This plasma coating process is already used industrially in various areas and thus offers an optimal basis for application in membrane production.

Promising membranes have already been produced which exhibit very good pure gas properties. For practical use, however, the membrane behaviour in the mixed gas is decisive, since a number of non-ideal effects can occur there. In this work, this behaviour is to be investigated and broken down for different binary gas mixtures.
