SBIR Phase II: Clean and Efficient Catalytic Combustion of Methane

这个小型企业创新研究(SBIR)二期项目将优化甲烷燃烧用高比表面积(SSA)催化涂层的性能和耐久性，并将其开发扩展到原型燃烧室应用中。在第一阶段，通过开发一种新型的短通道长度、高单元密度(SCL-HCD)金属整体催化剂基板的高比表面积涂层，降低了甲烷燃料催化燃烧室的起燃温度和稳定运行。成功地演示了两种催化燃烧器结构。在第二阶段，将在大气和高压下对这些概念进行更广泛的测试，目的是将燃烧室纳入燃气轮机。第二阶段的工作将包括通过与燃气轮机制造商的产品设计小组互动进行设计、应用分析和可行性评估。该技术的成功开发使天然气燃气涡轮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实现了商业化。此外，研制高SSA涂料在快速热响应型SCL-HCD汽车催化转化器中也具有应用价值。

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.
