SBIR Phase I: Improved Materials for Hydrogen-Purification Membranes

*96-61081布莱恩这个项目致力于氢分离膜新材料的开发。第一阶段的目标是证明一组新的金属合金可以设计成以更低的成本提供高的氢渗透性，通过操纵两个最强烈地控制钯合金的氢渗透性的因素，晶格间距，以及有利的电子密度对钯4d电子带的贡献。候选合金将被制造并进行成本归一化氢渗透性测试。第一阶段有望证明这种方法在开发新的高性能、低成本氢渗透合金方面的有效性。低成本、高性能的金属膜将适用于目前的金属膜无法经济地解决的广泛应用。这些应用包括金属的热处理、玻璃的生产、食用脂肪和食用油的氢化、石油精炼、烯烃和芳烃制造、半导体制造商以及氢作为替代燃料的开发。***

*** 96-61081 Bryan This project addresses development of new materials for hydrogen-separation membranes. The objective of Phase I is to demonstrate that a new group of metal alloys can be designed to deliver high hydrogen permeability at reduced cost via manipulation of the two factors that most strongly govern hydrogen permeability in palladium alloys the lattice spacing, and the favorable donation of electron density to the palladium 4d electron band. Candidate alloys will be fabricated and tested for cost-normalized hydrogen permeability. Phase I is expected to demonstrate the validity of this approach for developing new high-performance, low-cost hydrogen-permeable alloys. Low-cost, high performance metal membranes will be practical for a broad range of applications that cannot be economically addressed with current metal membranes. These applications include the heat-treating of metals, production of glass, hydrogenation of edible fats and oils, petroleum refining, olefins and aromatics manufacture, semiconductor manufacturer, and the development of hydrogen as an alternative fuel. ***
