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

这个小企业创新研究第一阶段项目涉及开发一种催化剂，以控制使用天然气涡轮机的联合循环发电厂（天然气发电厂）的氮氧化物排放。Guild Associates开发了一种环境催化剂，用于控制含氮化合物的排放。这种催化剂的独特之处在于它能够破坏这类化合物，其中包括NH3，而不产生NOx。最近研究了该催化剂在潮湿空气中NH3存在下减少NOx的能力。在过量NH3存在的情况下，催化剂能够完全还原NOx而没有NH3滑落。由于催化剂能够直接将过量的NH3还原为N2和H2O，从而防止了NH3的滑落。第一阶段SBIR提案的目标是在与天然气发电厂应用相一致的条件下评估该催化剂，并对催化剂进行修改以解决可能存在的缺点。这项工作的成功完成将带来一种简单、低成本的技术，用于控制天然气发电厂的氮氧化物排放，而不会产生NH3泄漏。目前的技术无法在不产生大量NH3漏失的情况下将氮氧化物排放量降低到90%以上。如果在这项努力下开发的新型催化剂被证明是成功的，发电厂将提供低成本、简单的技术来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.
