【 摘 要 】

This quarterly technical progress report will summarize work accomplished for Phase 1 Program during the quarter January to March 2002. In task 1 improvements to the membrane material have shown increased flux, and high temperature mechanical properties are being measured. In task 2, composite development has shown that alternative fabrication routes of the substrate can improve membrane performance under certain conditions. In task 3, scale-up issues associated with manufacturing large tubes have been identified and are being addressed. The work in task 4 has demonstrated that composite OTM elements can produce oxygen at greater than 95% purity for more than 1000 hours of the target flux under simulated IGCC operating conditions. In task 5 the multi-tube OTM reactor has been operated and produced oxygen.
