This Small Business Innovation Research (SBIR) Phase II project will develop an innovative modular oxygen enrichment system. It is accepted that the reduction of cycle time can lead to a concurrent decrease in the mass of a sorptive separation system. However, ultra-rapid-cycle systems invariably create mechanical and physical challenges. Specifically, limiting factors are the operational lifetime of the mechanical components, and the micro diffusion rate of the adsorbent system. This project will remove these limitations by replacing mechanical valves with electro-kinetic pumps, and by utilizing microscale adsorbent structures that radically improve diffusion rates.Conventional air separation units exhibit a poor mass/output ratio, which contributes to high cost. Oxy-air combustion offers the possibility of significant fuel savings and other environmental benefits. The broad impact of this research is not only fuel savings attainable from improved combustion efficiency, but also application to other processes where oxygen is the rate limiting factor. Fuel cells, aquaculture, biomass conversion, and water treatment will also profit from this exportable technology.

该小型企业创新研究（SBIR）第二阶段项目将开发一种创新的模块化富氧系统。周期时间的缩短可导致吸附分离系统质量的同时降低，这是公认的。然而，超快速循环系统总是会产生机械和物理挑战。 具体地，限制因素是机械部件的操作寿命和吸附剂系统的微扩散速率。 该项目将通过电动泵取代机械阀，并通过使用从根本上提高扩散速率的微型吸附剂结构来消除这些限制。传统的空气分离装置表现出较差的质量/输出比，这导致成本高。氧-空气燃烧提供了显著节省燃料和其他环境效益的可能性。 这项研究的广泛影响不仅是通过提高燃烧效率来节省燃料，而且还应用于氧气是速率限制因素的其他过程。 燃料电池、水产养殖、生物质转化和水处理也将受益于这种可出口的技术。
