Verena Kramer, Technische Universität Berlin, Technische Universität Berlin, Matthias Kraume
In this work solubility selective mixed matrix membranes consisting of silicon polymers and activated carbon are investigated for transport and separation properties of n-butane and methane. For mathematical description of the permeation process a new model is developed based on one-dimensional discretisation of the separation layer. This is an innovative approach for modelling of mixed matrix membranes and can also be applied for other systems than the one investigated in this work. For the

Based on experimental and modelling results, mass transfer mechanisms within the mixed matrix membrane are identified, membrane materials are evaluated and the influences of certain parameters on membrane performance are forecasted.
