This NIH SBIR Phase I research will study the feasibility of using our recently developed large micropore volume activated carbon (LMPV-AC) material for medical oxygen gas storage applications. The proposed research is based on the fact that the proposed material possesses large micropore volume with relatively uniform pore size distribution and is able to adsorb/desorb a large amount of oxygen gas at a relatively small pressure. It is estimated that the proposed system could achieve the same oxygen storage density as that of a 150atm compressed cylinder with just 10-15atm pressure. With such low storage pressure, oxygen storage for home oxygen therapy will be safer, cheaper, and more convenient. It is also possible that the proposed system would be allowed in commercial airplanes, and the oxygen refill can be done at home safely with an oxygen concentrator. During Phase I research, the proposed carbon material will be optimized and characterized to achieve the best oxygen storage performance; the material's oxygen adsorption/desorption isotherms will be measured; the kinetic oxygen charge/discharge properties and related heat management will be studied; and the preliminary design of a LMPV-AC based low-pressure high-density oxygen storage system will be performed. The Phase I work will lay the background for the Phase II work, which will further develop and commercialize the proposed system. If successful, this research will lead to a low-pressure high-density oxygen gas storage system for the home oxygen therapy applications. With this system, potentially hazardus high pressure gas cylinders and troublesome liquid oxygen canisters can be eliminated. Therefore, the proposed technology will benefit to the home oxygen therapy patients, which is estimated to be 0.5 to 0.8 million people in the United States.

这项NIH SBIR I期研究将研究使用我们最近开发的大型 用于医用氧气储存应用的微孔体积活性炭（LMPV-AC）材料。拟议的研究是基于以下事实：所提出的材料具有相对均匀的孔径分布的大型微孔体积，并且能够在相对较小的压力下吸附大量的氧气。据估计，所提出的系统可以达到与仅10-15ATM压力的150ATM压缩缸相同的氧气存储密度。在如此低的存储压力下，家庭氧疗法的氧气存储将更安全，更便宜，更方便。也有可能在商业飞机中允许拟议的系统，并且氧气填充物可以是 用氧气集中器安全地在家中完成。 在第一阶段的研究中，提出的碳材料将得到优化和表征，以达到最佳的氧气储存性能。将测量材料的氧吸附/解吸等温线；将研究动力学电荷/排放特性和相关的热量管理；将执行基于LMPV-AC的低压高密度氧气存储系统的初步设计。第一阶段的工作将为第二阶段工作提供背景，这将进一步开发和商业化拟议的系统。 如果成功，这项研究将导致家庭氧疗法应用的低压高密度氧气存储系统。使用该系统，可以消除潜在的Hazardus高压气缸和麻烦的液体氧气罐。因此，拟议的技术将受益于家庭氧疗法患者，据估计，在美国，这一患者估计为0.5至80万。
