Heterogeneous catalysis is used in the chemical and petroleum industries for the manufacture of a variety of valuable products. Inorganic membrane reactors combine the catalytic reaction and separation functions into one unit. The attractiveness of these reactors arises from their substantially improved performance for reversible reaction systems; as the products are continuously removed the reactions can shift to higher conversions, not limited by equilibrium considerations. For a fixed total amount of catalyst, the question arises as to how it should be distributed within the membrane so that the membrane reactor performance (for example reaction rate, product purity, etc.) is optimized. This is the motivation for this research project. The PI plans to conduct a combined theoretical-experimental study, to investigate the performance of catalytic membrane reactors with controlled catalyst distribution. Theoretical work will identify the optimal catalyst distribution required to maximize specific performance indices (for example, reactant conversion, product purity, etc.). This will include analysis of membrane reactors where the catalyst is distributed in a controlled manner along the membrane thickness as well as along the reactor length. Experimental work will be directed towards preparing and testing such membranes, and will permit a quantitative comparison with theoretical predictions.***//

多相催化在化工和石油工业中用于生产各种有价值的产品。无机膜反应器将催化反应和分离功能结合在一个单元中。这些反应器的吸引力来自于它们显著改善了可逆反应系统的性能；随着产物的不断去除，反应可以转移到更高的转化率，而不受平衡考虑的限制。对于固定总量的催化剂，问题是它应该如何分布在膜内，以便膜反应器的性能(如反应速度、产品纯度等)。是经过优化的。这就是本研究项目的动因。PI计划进行理论和实验相结合的研究，以考察催化剂分布受控的催化膜反应器的性能。理论工作将确定使特定性能指标(例如，反应物转化率、产品纯度等)最大化所需的最佳催化剂分布。这将包括对膜反应器的分析，在膜反应器中，催化剂以受控的方式沿膜厚度以及沿反应器长度分布。实验工作将针对这种膜的制备和测试，并将允许与理论预测进行定量比较。
