SBIR Phase I: Low Cost Manufacturing of Pollution Control Substrates

这个小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底，以减少大型柴油发动机和燃烧器的污染。 目前，这些基材是挤出的，因此在尺寸、形状和气流动力学方面受到限制。 因此，挤出基材需要昂贵的催化剂，并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颖的、环境友好的、低成本的制造方法来制造大型基板。 这些基材将具有改善的传热和传质性能，使基材能够快速达到未催化的操作温度。 由此产生的废气缓解系统将不依赖于贵金属催化剂，因此成本比目前可用的产品低得多。第一阶段的工作是针对测试，开发和基准测试一种新的制造技术。 这些制造方法将利用Errcive？公司先前在超低成本原材料方面的工作，创造了一种全新的减轻污染的产品。 这项研究的更广泛/商业影响包括：i）减少空气污染，ii）开发先进的制造技术，iii）将工业废物升级循环为高价值产品。 标准污染物（例如，颗粒物和氮氧化物）是健康危害，导致北方地区过早融化，是强有力的气候强迫因素。 降低标准污染物的浓度将产生各种积极的结果，包括改善空气质量和整体人口健康，特别是在城市，铁路站场和港口附近。 此外，最近的研究已经确定，PM和NOx可能是全球变暖的前五大物种之一。 PM在大气中的寿命（数周）比CO2的寿命（数十年）短得多。 因此，减少PM排放可以最快地减少全球变暖。PM和NOx几乎是全世界排放的？5000万台柴油发动机。 显著减少总排放量需要减轻世界？最古老，最大的发动机。 然而，现有技术的成本限制了大规模采用。 经济的废气缓解系统必须能够以不妨碍其采用的成本清洁这些排放流。 该项目旨在创建一个结合高性能和低成本的革命性系统。

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.
