SBIR Phase I: Catalyst for Near-Zero NOx Emissions from Natural Gas Fired Power Plants

该小型企业创新研究第一阶段项目涉及开发一种催化剂，以控制使用天然气燃气轮机的联合循环发电厂（天然气发电厂）的NOx排放。 Guild Associates开发了一种用于控制含氮化合物排放的环境催化剂。 该催化剂的独特之处在于它能够破坏包括NH3在内的这类化合物，而不会产生NOx。 最近研究了该催化剂在潮湿空气中存在NH3的情况下还原NOx的能力。 在过量NH3存在下操作，催化剂能够完全还原NOx而没有NH3泄漏。 由于催化剂能够将过量的NH3直接还原成N2和H2O，因此防止了NH3泄漏。 第一阶段SBIR提案的目的是在与天然气发电厂应用一致的条件下评估该催化剂，并修改催化剂以解决可能的缺点。 这项工作的成功完成将导致一种简单、低成本的技术，用于控制来自天然气燃烧发电厂的NOx排放，而没有NH3泄漏。 如果在这一努力下开发的新型催化剂被证明是成功的，发电厂将获得低成本、简单的技术，以满足日益严格的氮氧化物排放水平。

This Small Business Innovative Research Phase I project involves the development of a catalyst to control NOx emissions from combined cycle power plants using natural gas fired turbines (natural gas fired power plants). Guild Associates has developed an environmental catalyst for the control of nitrogen-containing compound emissions. The catalyst is unique in that it is able to destroy this class of compounds, which includes NH3, without generating NOx. The catalyst was recently investigated for its ability to reduce NOx in the presence of NH3 in humid air. Operating in the presence of excess NH3, the catalyst was able to completely reduce NOx without NH3 slip. NH3 slip is prevented because the catalyst is able to directly reduce the excess NH3 to N2 and H2O. The objective of this Phase I SBIR proposal is to evaluate this catalyst under conditions consistent with the natural gas fired power plant application and to modify the catalyst to address possible shortcomings. Successful completion of this effort will lead to a simple, low cost technology for control of NOx emissions from natural gas fired power plants without NH3 slip.Current technologies are not capable of reducing NOx emissions to greater than 90% without significant levels of NH3 slip. Should the novel catalyst developed under this effort prove successful, power plants will be provided with low cost, simple technology to meet increasingly tighter NOx emissions levels.
