SBIR Phase II: Clean and Efficient Catalytic Combustion of Methane

该小型企业创新研究（SBIR）第二阶段项目将优化甲烷燃烧高比表面积（SSA）催化涂层的性能和耐用性，并将其开发扩展到原型燃烧器应用中。 在阶段I中，通过开发用于新型短通道长度、高孔密度（SCL-HCD）金属整料催化剂基底的高表面积涂层，证明了甲烷燃料催化燃烧器构造的降低的起燃温度和稳定的操作。 两个催化燃烧室的配置成功地证明。 在第二阶段，将在大气和高压下对这些概念进行更广泛的试验，目的是将燃烧室纳入燃气涡轮机发动机。 通过与燃气涡轮机制造商的产品设计小组的互动，设计、应用分析和可行性评估将包括在第二阶段的工作中。 该技术的成功开发使得用于天然气燃料燃气涡轮机发动机的超低排放催化燃烧技术在分布式发电和天然气管道压缩机驱动器等商业应用中能够商业化。 此外，高SSA涂层的开发在快速热响应的SCL-HCD汽车催化转化器中具有应用价值。

This Small Business Innovation Research (SBIR) Phase II project will optimize the performance and durability of high Specific Surface Area (SSA) catalytic coatings for methane combustion, and extend their development into prototype combustor applications. In Phase I, reduced lightoff temperature and stable operation of methane-fueled catalytic combustor configurations were demonstrated by developing a high surface area coating for a novel Short Channel Length, High Cell Density (SCL-HCD) metal monolith catalyst substrate. Two catalytic combustor configurations were successfully demonstrated. During Phase II, more extensive testing of these concepts, both at atmospheric and at high pressure, will be performed with the aim of incorporating the combustor into a gas turbine engine. Design, applications analysis, and viability assessment through interaction with product design groups at gas turbine manufacturers will be included in this Phase-II effort. The successful development of this technology is enabling commercialization of ultra-low emission catalytic combustion technology for natural-gas-fueled gas turbine engines in commercial applications such as distributed power generation and natural gas pipeline compressor drivers. In addition, developing the high SSA coating has application in fast thermal response SCL-HCD automotive catalytic converters.
