9360018 Zamansky This is a Phase I award under the Small Business Innovation Research Solicitation. It is a novel approach to the control of nitrogen oxides from combustion flue gases based upon the oxidation of nitric oxide (NO) to nitrogen dioxide, and removal of the latter in slightly modified calcium-based sulfur-dioxide scrubbers. Nitric oxide is converted to nitrogen dioxide by reaction with sulfur dioxide and oxygen in the gas phase; the reactants are already present in the off-gases from sulfur-containing coal. This effort provides a laboratory-scale feasibility study of the process at reaction times and temperatures suitable to application in the flues of boilers and furnaces. Removal of the oxides of sulfur and nitrogen from combustion flues is essential to improvement of air quality and reduction of acid rain. This effort offers the prospect of controlling both sets of oxides at once, with a technology that might be a suitable retrofit to existing sulfur-control systems.

小行星9360018 这是小企业创新研究征集下的第一阶段奖项。 这是一种控制燃烧烟气中氮氧化物的新方法，其基于将一氧化氮（NO）氧化成二氧化氮，并在略微改进的钙基二氧化硫洗涤器中去除二氧化氮。 一氧化氮通过与二氧化硫和氧气在气相中反应转化为二氧化氮;反应物已经存在于含硫煤的废气中。 这项工作提供了一个实验室规模的可行性研究的过程中的反应时间和温度适合应用于烟道锅炉和熔炉。 去除燃烧烟道中的硫和氮氧化物对于改善空气质量和减少酸雨至关重要。 这项工作提供了前景控制两套氧化物一次，与技术，可能是一个合适的改造现有的硫控制系统。
