SBIR Phase II: Compact membrane reactors for high-purity hydrogen

小型企业创新研究(SBIR)第二阶段项目将开发微型通道膜重整器，以从气体和液体燃料中生产纯氢。目前，燃料重整碳氢燃料以生产高纯度氢气是克服现有氢气基础设施不足的唯一手段。燃料处理器必须能够快速启动，快速满足需求，耐硫，并在广泛的转化率范围内高效运行。使用微型通道重整器，在各个重整阶段的生产现场选择性地用膜去除氢气，将导致重整反应的效率、热力学和动力学的提高。如果成功，建议的膜重整系统将降低系统复杂性，降低成本，并使控制、监测和瞬时响应变得容易。拟议的技术在高纯度商用氢的商业部门以及用于便携式电力和分布式发电的氢燃料电池的民用和军用部门具有重要的商业机会。还将获得关于透氢膜的行为以及它们在高温、耐硫、紧凑型燃料重整装置中用于生产高纯度氢气的宝贵科学和技术理解。

The Small Business Innovation Research (SBIR) Phase II project will develop mini-channel membrane reformers to produce pure hydrogen from gaseous and liquid fuels. Fuel reforming of hydrocarbon fuels to yield high purity hydrogen is, at present, the only means for overcoming the lack of an established infrastructure for hydrogen. Fuel processors must be able to start up quickly, follow demand rapidly, be tolerant to sulfur, and operate efficiently over a wide range of conversion rates. The use of mini-channel reformers, with selective membrane removal of hydrogen at the site of production within the individual reformer stages, will lead to improved efficiency, thermodynamics and kinetics of reforming reactions. If successful, the proposed membrane reformer system will decrease system complexity, reduce costs, and allow ease of control, monitoring and transient response. The proposed technology has significant business opportunities in the business sector for high-purity merchant hydrogen, and in the civilian and military sectors for hydrogen fuel cells, used in portable power and distributed generation. Valuable scientific and technological understanding will also be gained about the behavior of hydrogen-permeable membranes and their use in high-temperature, sulfur-resistant, compact fuel reformers to produce high-purity hydrogen.
