Ceramic Membranes for Catalytic Reaction Applications

摘要- Tsotsis 无机膜一直是液体和气体分离的研究主题。 对这种膜的兴趣是由于它们独特的热和机械性能以及它们的化学和微生物抗性。 无机膜如今在食品和制药工业、废水处理和催化等领域得到应用。 膜反应器联合收割机将反应和分离结合在单个单元操作中。 膜从反应区选择性地去除物质，否则这些物质将在化学上或动力学上限制反应进程。 这又增加了反应器产率，并导致下游分离要求降低和操作成本降低。 该项目的目标是更好地了解液体大分子如何在小孔中扩散和反应（典型的是在膜和催化剂中发现的）。 主要调查者的兴趣是石油液体。 他们计划调查陶瓷膜反应器技术在石油和沥青质加氢处理领域的适用性，并深入研究相关的技术问题和问题。 两种类型的氧化铝陶瓷膜将被研究，膜由铝的阳极氧化，主要用于基本的运输和反应的调查，和膜由溶胶-凝胶技术制备，类似的调查，但也用于测试的催化膜反应器的概念。 这两种膜具有几乎单峰的孔径分布，并显示出优异的分离功能，但具有截然不同的表面性质和独特的孔结构。 \& 1z 控制INI d `3 Wintutordat @ j CALC EXE @ j！@ SOLID2 BMP 1vX分析员SBMP P：.vX CHITZ BMP @ j“M PBRUSH EXE @ j 'P 丁 WAV @ j“N-埃及 BMP @ j #v 方形BMP @ j 4v 摘要- Tsotsis 无机膜一直是液体和气体分离的研究主题。 对S的兴趣 0 2 } 2 ! ! !

Abstract - Tsotsis Inorganic membranes have been the subject of research for liquid and gas separations. The interest in such membranes is due to their unique thermal and mechanical properties and their chemical and microbiological resistance. Inorganic membranes are today finding applications in areas like the food and pharmaceutical industries, in waste water treatment and in catalysis. Membrane reactors combine reaction and separation in a single unit operation. The membrane selectively removes from the reaction zone species, which would otherwise thermodynamically or kinetically limit the reaction progress. This, in turn, increases the reactor yield and results in diminished downstream separation requirements and smaller operational costs. The goal of this project is to gain a better understanding of how liquid macromolecules diffuse and react in small pores (typical of those found in membranes and catalysts). The principal invetigators' interests are in petroleum liquids. They plan to investigate the applicability of ceramic membrane reactor technology in the area of oil and asphaltene hydroprocessing and to study, in depth, the relevant technical questions and issues. Two types of alumina ceramic membranes will be studied, membranes prepared by anodic oxidation of aluminum, primarily for fundamental transport and reaction investigations, and membranes prepared by the Sol-Gel technique, for similar investigations, but also for testing the catalytic membrane reactor concept. Both kinds of membranes have a virtually unimodal pore size distribution and show excellent separatory functions, but have di stinctly different surface properties and unique pore structures. \& 1z CONTROL INI d `3 WINTUTORDAT @ j CALC EXE @ j !@ SOLID2 BMP 1vX ANALYSTSBMP P :.vX CHITZ BMP @ j " M PBRUSH EXE @ j 'P DING WAV @ j "N- EGYPT BMP @ j #v SQUARES BMP @ j 4v Abstract - Tsotsis Inorganic membranes have been the subject of research for liquid and gas separations.
