ABSTRACTPI: Eduardo E. Wolf Institution: University of Notre DameProposal Number: 0224435Research:The short term objective of this work is to study the direct partial oxidation of propane to acrolein, a chemical intermediary, using a dual membrane reactor. This reactor has unique characteristics that can increase product yield, which is typically low for the propane to acrolein reaction when carried out in a conventional fixed bed reactor. The use of alkanes, such as propane, for the direct conversion by partial oxidation to acrolein is more attractive than the current process that uses propylene, a more expensive feedstock.The long term objective is to study, evaluate and optimize the capabilities of the dual bed membrane reactor. The reactor consists of an inert membrane, placed concentrically to the reactor tube wall. Catalyst is located between the membrane and the reactor wall and the membrane acts as a barrier between the oxidant (air/oxygen) and the reducing feed (propane) thus reducing the danger of flammability encountered in reactors with premixed feeds. What makes the dual bed membrane reactor unique is that it has two catalyst beds fed separately so that reaction conditions can be independently controlled in each bed. This is different from two reactors in series in that in the dual bed membrane reactor the two catalyst beds are connected. The gas phase intermediates emerging from the first bed are utilized in the second bed. It thus allows the independent control of temperature, catalysts, gas phase intermediates, and residence time in a single reactor.Impact:If the results are successful, the technology could be extended to other alkane functionalization reactions to provide a less energy intensive technology for the environmentally clean production of oxygenate intermediates for the chemical industry. The project will integrate research and teaching both at the graduate and undergraduate level.

AbstractPI：Eduardo E. Wolf Institution：Notre University DamePropossosement：0224435研究：这项工作的短期目标是使用双膜反应器研究丙烯丙烯丙烯丙烯丙烯丙烯丙烯丙基的直接部分氧化。 该反应器具有独特的特性，可以增加产物的产量，而在常规的固定床反应器中进行丙烯丙烯蛋白反应的丙烷反应通常很低。 烷烃（例如丙烷）通过部分氧化为丙烯醛的直接转化比使用丙烯（一种更昂贵的原料）的过程更具吸引力。长期目标是研究，评估和优化双床膜反应器的功能。 反应器由惰性膜组成，将惰性膜浓度放在反应堆壁上。 催化剂位于膜和反应堆壁之间，膜充当氧化剂（空气/氧）与还原饲料（丙烷）之间的屏障，从而减少了用预馈入的反应堆在反应堆中遇到的易燃性的危险。 使双床膜反应器与众不同的是，它具有两个分别喂食的催化剂床，因此可以在每个床中独立控制反应条件。 这与串联的两个反应器不同，在双床膜反应堆中，两个催化床连接。 第一张床出现的气相中间体在第二张床中使用。 因此，它可以独立控制单个反应器中的温度，催化剂，气相中间体和停留时间。如果结果成功，则该技术可以扩展到其他烷烃功能化反应，以提供较低的能源密集型技术，以使环境清洁化学工业的氧化中间体生产。 该项目将在研究生和本科层面整合研究和教学。
