The present project focuses on the development of novel techniques for the synthesis of microporous self-supported zeolite membranes. Our recent syntheses utilize a nanocrystalline filer residue from industrial silane production, serving as silicate source. These attempts successfully led to the formation of self-supported SOD, LTA, SOD-LTN and LTA-FAU membranes. Additional findings provide high significance for future improvement of SOD membranes by dynamic exchange of Na+OH- ion pairs and H2O molecules, and by results concerning the avoidance of carbonate enclathration. The preliminary results lead to further fundamental scientific issues, namely (1) an improvement of the membrane density and (2) investigating the utilization potential of commercially available silicate sources instead of the filter residue. Experiments with respect to the issues (1) and (2) are intended to be the subject of final investigations, which will provide further necessary insights into the novel synthesis technique of self-supported zeolite membranes.

本项目的重点是开发新的技术，用于合成微孔自支撑沸石膜。我们最近的合成利用来自工业硅烷生产的纳米晶体过滤器残留物作为硅酸盐来源。这些尝试成功地导致形成自支撑SOD、LTA、SOD-LTN和LTA-FAU膜。另外的研究结果提供了高的意义，为未来的改善SOD膜的动态交换Na+OH-离子对和H2O分子，并通过有关的结果，避免碳酸盐enclethration。初步结果导致进一步的基本科学问题，即（1）膜密度的提高和（2）研究商业上可获得的硅酸盐源而不是滤渣的利用潜力。关于问题（1）和（2）的实验旨在成为最终研究的主题，这将为自支撑沸石膜的新合成技术提供进一步必要的见解。
