What is it about?
In this paper, we report on the preparation of a new facilitated transport membrane of polyurethane containing silver nanoparticles (PUAg) for propane/propylene separation. We investigated the propylene and propane sorption in this membrane aiming at their selective separation from C3s mixtures. The PUAg membrane was successfully prepared and the sorption study showed that the propylene solubility resulted more than 4 times higher than the one observed for the pure PU membrane, revealing the high affinity between silver and propylene. Furthermore, the ideal solubility selectivity of PUAg membrane resulted 24.4, indicating that there is a good potential for an industrial application aiming at the separation of propylene/propane.

Why is it important?
The paper should be of interest to readers in the areas of: polymeric and mixed matrix membranes, nanoparticles, polymer transport properties and gas separation techniques because we report the application of a novel polymer membrane in gas separation. The sorption study indicate the potential of this membrane for gas separation industry.
Perspectives
