This Small Business Innovation Research Phase I project will investigate the use of novel manufacturing methods to fabricate porous ceramic substrates for reducing pollution from large diesel engines, and burners. Currently, these substrates are extruded, and are thus constrained in size, shape, and gas flow dynamics. As a result, extruded substrates require expensive catalysts, and do not easily scale to the largest, most polluting engines. This project will seek to develop a novel, environmentally benign, low cost manufacturing method to make large substrates. These substrates will have improved heat transfer and mass transfer properties, enabling the substrates to reach uncatalyzed operation temperatures quickly. The resulting exhaust mitigation systems will not rely on precious-metal catalysts, and thus be much lower cost than currently available products. This Phase I effort is directed toward testing, developing, and benchmarking a new manufacturing technology. These fabrication methods will leverage Errcive?s prior work on ultra-low cost raw materials to create an entirely new type of pollution mitigation product. The broader/commercial impacts of this research include: i) reducing air pollution, ii) developing advanced manufacturing technology, and iii) upcycling industrial waste into high value products. Criteria pollutants (e.g., particulate matter and NOx), are health hazards, cause premature melting in Boreal regions, and are strong climate forcing agents. Reducing the concentrations of criteria pollutants will result in a variety of positive outcomes, including improved air quality and overall population health, particularly near cities, rail yards, and ports. Additionally, recent studies have determined that PM and NOx may be among the top five global warming species. The atmospheric lifetime of PM (weeks) is much shorter than that of CO2 (decades). Thus, mitigating PM emissions may yield the fastest reduction in global warming. PM and NOx are emitted by virtually all of the world?s ~50 million diesel engines. Appreciably reducing overall emissions requires mitigating the world?s oldest, largest engines. However, the cost of currently available technology prohibits wide scale adoption. An economic exhaust mitigation system must be capable of cleaning these emissions streams at a cost that does not prevent its adoption. This project is directed toward creating a revolutionary system that combines high performance and low cost.

这个小型企业创新研究第一阶段项目将研究使用新的制造方法来制造多孔陶瓷基板，以减少大型柴油发动机和燃烧器造成的污染。目前，这些衬底是挤压的，因此在大小、形状和气体流动动力学方面受到限制。因此，挤压基材需要昂贵的催化剂，而且不容易扩展到最大、污染最严重的发动机。该项目将寻求开发一种新的、环境友好的、低成本的制造方法来制造大型基板。这些底物将具有更好的传热和传质性能，使底物能够快速达到非催化操作温度。由此产生的废气减排系统将不依赖贵金属催化剂，因此成本比目前可用的产品低得多。这一阶段的工作旨在测试、开发和标杆一种新的制造技术。这些制造方法将利用Errcive？S先前在超低成本原材料上所做的工作，创造出一种全新的污染缓解产品。这项研究的更广泛的商业影响包括：i)减少空气污染，ii)开发先进的制造技术，以及iii)将工业废物升级为高价值产品。标准污染物(例如，颗粒物和NOx)是健康危害，在北方地区造成过早融化，并且是强烈的气候强迫因素。降低标准污染物的浓度将产生各种积极结果，包括改善空气质量和总体人口健康，特别是在城市、铁路站场和港口附近。此外，最近的研究确定，PM和NOx可能是全球变暖的前五个物种之一。PM的大气寿命(周)远短于CO2的大气寿命(几十年)。因此，减少PM排放可能会以最快的速度减少全球变暖。PM和NOx几乎是世界上所有柴油机的排放物？？S大约有5000万台柴油机。要想明显地减少总体排放，就需要减轻世界的压力？S是最古老、最大的发动机。然而，目前可用技术的成本阻碍了大规模采用。一个经济的尾气缓解系统必须能够以不妨碍采用的成本清洁这些排放流。该项目旨在创造一种结合高性能和低成本的革命性系统。
