SBIR Phase I: Catalytic Suppressor System for Reducing Diesel Emissions

这个SBIR项目将开发一种新的技术，用于去除和破坏柴油发动机尾气中的氮氧化物污染物。该项目将解决四个重要问题。第一个问题是将沸石涂层应用于具有正确化学成分和孔径分布的网状催化剂载体。第二个问题将是通过离子交换过程掺杂沸石金属，然后应用稳定的纳米氧化物涂层来完成催化剂支撑体系。第三个问题将是在排气流中放置的设计架构。第四个也是最后一个问题将是测量系统并评估它们的有效性、成本、生命周期和制造的便利性。拟议项目的更广泛/商业影响将是一个低成本的排放减排装置，可以很容易地改装到目前运行的柴油动力车辆上，具有排放控制功能。氮氧化物、颗粒物、挥发性有机碳和一氧化碳的减少对健康有相关的好处。美国环保署估计，使用清洁燃烧的越野柴油发动机可以从空气中去除超过8.6万吨的微粒和44万吨的氮氧化物。

This SBIR project will develop a new technology for the removal and destruction of NOx pollutants from diesel engine exhaust. Four important issues will be addressed in the project. The first issue will be applying a zeolite coating to reticulated catalyst supports with the correct chemical composition and pore size distribution. The second issue will be doping the zeolite metal with an ion exchange process followed by application of a stabilizing nano-oxide coating to complete the catalyst support system. The third issue will be the design architecture for placement in the exhaust stream. The fourth and final issue will be measuring the systems and evaluating their effectiveness, cost, life cycle, and ease of manufacture.The broader/commercial impacts of the proposed project will be a low-cost emission abatement device that can be easily retrofitted to currently operating diesel powered vehicles with emission control capabilities. The reduction of nitrogen oxides, particulate matter, volatile organic carbons, and carbon monoxide has associated health benefits. EPA estimates that over 86,000 tons of particulates and 440,000 tons of NOx can be removed from the air with the use of clean burning off-road diesel engines.
