Polypropylene is the 2nd largest petrochemical commodity and 5th largest produced material in the US. The key step in propylene production is propylene/propane separation achieved by energy intensive cryogenic distillation method. Membrane separation technology is a more energy efficient solution to the separation problem, but propylene perm-selective polymer or inorganic membranes are not stable for this application. Recent study in the principal investigator's laboratory shows a new group of membranes, zeolitic-imidazolate framework (ZIF), to have desired separation properties and stability for the application. ZIFs are highly tailorable with a wide range of chemical, textural, and crystalline properties that can be implemented into a number of other technological applications. The activities proposed in this project are directed towards development of membranes that can be scaled up for industrial olefin/paraffin separation. This project will gain much insight into the fundamental nature of material selection for membrane supports and synthesis and properties of ZIF membranes on scalable supports. The project will increase learning and understanding in membrane science and engineering to the academic community, while also delivering valuable information on how to transition such novel materials into useful industrial applications.

聚丙烯是美国第二大石化商品，在美国第五大生产材料。丙烯产生的关键步骤是通过能量密集型低温蒸馏法实现的丙烯/丙烷分离。膜分离技术是针对分离问题的更节能的解决方案，但是对于此应用，丙烯允许选择性聚合物或无机膜不稳定。首席研究者实验室的最新研究表明，一组新的膜，沸石 - 咪唑酸酯框架（ZIF）具有所需的分离特性和应用的稳定性。 ZIF具有高度量身定制的，具有多种化学，纹理和结晶特性，可以在许多其他技术应用中实施。该项目中提出的活动是针对膜的发展，这些膜可以扩展到工业烯烃/石蜡分离。该项目将深入了解材料选择的基本性质，用于膜支持，ZIF膜在可扩展支持上的合成和特性。该项目将向学术界增加膜科学和工程学的学习和理解，同时还提供有关如何将这种新型材料过渡到有用的工业应用的有价值的信息。
