SBIR Phase I: Four-way Catalytic Converter for Lean Burn Diesel Engines

这项小型企业创新研究（SBIR）第一阶段项目将展示一种新型四路催化转化器的技术和商业可行性，该转化器基于直接应用于现有催化转化器整体内壁的高表面积纳米材料。虽然目前正在进行将柴油微粒过滤器和氧化催化剂整合在一起的研究，但很少有研究解决所有四个组成部分（一氧化碳氧化、碳氢化合物氧化、碳微粒物质（PM）的捕获和破坏以及氮氧化物的减少）的整合问题。这项研究的更广泛/商业影响是，2013年严格的柴油排放标准要求将成为法律。这些新规定将在颗粒大小和颗粒数量方面影响碳排放。虽然有满足即将到来的PM法规的建议，但没有一个积极整合催化转化器的所有必要功能。因此，该项目催化转化器结构在美国的潜在商业价值是显著的。欧洲市场的机会可能更大，因为柴油发动机在欧洲更普遍。

This Small Business Innovation Research (SBIR) Phase I project will demonstrate the technical and commercial viability of a novel four-way catalytic converter for lean burn diesel applications that is based on high-surface area nanomaterials applied directly to the inner walls of existing catalytic converter monoliths. While there is ongoing research to integrate diesel particulate filters and the oxidation catalyst, there is little research addressing the integration of all four components (oxidation of carbon monoxide, oxidation of hydrocarbons, capture and destruction of carbon particulate matter (PM) and reduction of NOx.The broader/commercial impacts of this research are that in 2013 strict requirements for diesel emissions standards will become law. These new regulations will effect carbon emissions both in terms of particle size and number of particles. While there are proposals to meet impending PM regulations, none actively integrate all the required functions of a catalytic converter. Therefore the potential U.S. commercial value of the catalytic converter structure from this project is significant. The European market opportunity may be larger since diesel engines are more prevalent in Europe.
