Abstract: Over the past decades, membrane technology has matured into an established technology for many energy-intensive chemical separations. Whereas conventional polymeric membranes are cheap and processable, they often suffer from aging issues and an intrinsic permeability/selectivity trade-off. On the other hand, inorganic membranes prepared from zeolites, MOFs and other crystalline microporous materials, typically display better separation performances but tend to be brittle and more expensive, and possess poor processability and scalability. Mixed-matrix membranes (MMMs), consisting of fillers embedded in a polymeric matrix, aim at combining the selectivity/permeability performance, robustness and non-aging properties of the filler with the ease to process, handle and upscale of the polymer. However, combining all in one single material has proven very challenging.

Zeolites could be an ideal membrane material, as they have well-defined, rigid porous systems and outstanding thermal and chemical stability. Obtaining ultra-high zeolite loadings (≥50 wt.%) while guaranteeing a defect-free polymer-zeolite interface in combination with a highly selective zeolite and appropriate glassy polymer matrix is essential to create high-performance membranes for a variety of the most critical separation challenges. To approach next-generation molecular separation membrane technology, we developed ultra-high zeolite loading MMMs that combine molecular sieving with desired chemical interactions. By selecting the proper fillers and manipulating the interaction environment in their ångström-sized porous systems, we developed the high-performance zeolite-filled membranes, thus trying to open the door to developing the well-processable, robust, and economical high-performance MMM platform for industrial-relevant molecular separations.

Biography: Xiaoyu Tan is a post-doctoral researcher in Prof. Ivo Vankelecom’s Membrane Technology Group at KU Leuven, Belgium, where he obtained his PhD degree in developing high-performance membranes for gas and liquid applications. Xiaoyu earned his B.Sc. degree in Applied Chemistry from Dalian University of Technology, China. He got his M.Sc. degree in Chemical Engineering at KAUST, Saudi Arabia, where he started his membrane research under Prof. Klaus-Viktor Peinemann’s guidance, and later he worked as a research engineer in the Technology and Innovation Center of SABIC in Riyadh for polymer development until he started his PhD research in MTG, KU Leuven. Xiaoyu now focuses on developing zeolite-filled membranes for the industrial-relevant molecular separation challenges.
