ABSTRACTProposal No: 9615754Proposal Type: GOALIPrincipal Investigator Theodore T. TsotsisAffiliation: University of Southern CaliforniaThis grant is awarded through the Interfacial, Transport and Separations Processes Program of the Chemical and Transport Systems Division, and the NSF Grant Opportunities for Academic Liaison with Industry (GOALI) Program. The Principal Investigator is Dr. Theodore Tsotsis of the University of Southern California. An academic and industrial collaborative research program is to be implemented aimed at developing a better fundamental understanding of the phenomena involved during the preparation of carbon molecular sieve (CMS) membranes. These membranes show excellent promise for many reactor and separation applications and are made via the carbonization in inert and/or reactive atmospheres of polymeric thin films which are either self-supported or coated on various porous substrates. The emphasis in this project is the understanding of the factors in the preparation procedure which are critical to the ability of these materials to effect separation of mixtures based on differences in molecular mobility within the membrane.Carbon molecular sieve membranes have tremendous potential in the separation of hydrocarbon and reformate mixtures. The ability to tailor the structure of a particular membrane to fit a particular separation and /or reactor application will greatly enhance the technological significance of these systems and expand their use into many new applications. A key requirement here is the development of predictive models of the pore structure and of transport and sorption characteristics of reactant mixtures. This is a main area of emphasis in the project, which will significantly advance the technological base in this area.

摘要提案编号：9615754提案类型：GOALI首席研究员Theodore T. tsotsis隶属于南加州大学。该资助通过化学和运输系统分部的界面、传输和分离过程项目以及NSF与工业界学术联络资助机会（GOALI）项目获得。首席研究员是南加州大学的Theodore Tsotsis博士。一项学术和工业合作研究计划将实施，旨在更好地了解碳分子筛（CMS）膜制备过程中涉及的现象。这些膜在许多反应器和分离应用中表现出良好的前景，并且是通过在惰性和/或反应气氛中碳化的聚合物薄膜制成的，这些薄膜要么是自支撑的，要么是涂覆在各种多孔基板上。本项目的重点是了解制备过程中的因素，这些因素对这些材料根据膜内分子迁移率的差异影响混合物分离的能力至关重要。碳分子筛膜在分离烃类和重整油混合物方面具有巨大的潜力。定制特定膜结构以适应特定分离和/或反应器应用的能力将大大提高这些系统的技术意义，并将其应用到许多新的应用中。这里的一个关键要求是发展孔隙结构和反应物混合物的传输和吸附特性的预测模型。这是该项目的一个主要重点领域，它将大大推进该领域的技术基础。
