Catalytic Membrane Technology for the Conversion of Greenhouse Gases

S.Ted Oyama教授将研究甲烷与二氧化碳的干式重整反应，以产生合成气(一氧化碳和氢气)。该催化反应将在金属、加勒比和磷酸盐形式的膜支载的镍和钨上进行。CVD改性的Vycor和氧化铝无机膜将通过在高温下选择性地分离氢来为反应提供额外的驱动力。该项目将涉及催化剂的开发、膜的表征和对氢的选择性的研究、各种高压下的动力学测量、同位素替代的机理研究以及催化膜反应器系统的建模。这项研究的结果可能会影响天然气作为化学源的使用程度，并为二氧化碳的修复提供一条途径。这项提议由化学和运输系统部门的以下项目资助：动力学、催化和分子过程；过程和反应工程；以及分离和提纯过程。

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.
