Professor S. Ted Oyama will study the dry reforming of methane with carbon dixode to produce synthesis gas (carbon monoxide and hydrogen). This catalytic reaction will be run on membrane-supported Ni and W in the metallic, caribidic and phosphidic form. The CVD-modified Vycor and alumina inorganic membranes will provide additional driving force for the reaction by selective separation of hydrogen at high temperature. The project will involve catalyst development, membrane characterization and investigation of their selectivity to hydrogen, kinetics measurement at various high pressures, mechanistic investigation by isotopic substitution, and modeling of the catalytic membrane reactor system. The outcome of this research may impact the extent of use of natural gas as a chemical source, and provide a pathway for carbon dioxide remediation. This proposal is funded by the following program of the Chemical and Transport Systems Division: Kinetics, Catalysis and Molecular Processes; Process and Reaction Engineering; and Separation and Purification Processes.

S. ted Oyama教授将研究甲烷用碳dixode的干燥改革，以产生合成气体（一氧化碳和氢）。 该催化反应将以金属，加勒比尼和磷化形式的膜支持的Ni和W进行。 CVD修饰的Vycor和氧化铝无机膜将通过在高温下选择性分离氢为反应提供额外的驱动力。 该项目将涉及催化剂的发育，膜表征和研究其对氢的选择性，各种高压下的动力学测量，同位素取代的机械研究以及催化膜反应堆系统的建模。 这项研究的结果可能会影响天然气作为化学物质的使用程度，并为二氧化碳修复提供了途径。 该提案由化学和运输系统部的以下计划资助：动力学，催化和分子过程；过程和反应工程；以及分离和净化过程。
