项目摘要

This Small Business Innovative Research (SBIR) Phase II 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). During the Phase I effort, Guild Associates developed an environmental catalyst for the control of NOx emissions using NH3. Operating in the presence of excess (about 20-33%) NH3, the catalyst was able to achieve greater than 95% NOx reduction without NH3 slip. NH3 slip is avoided because the catalyst is able to simultaneously reduce the excess NH3 to N2 and H2O. The objective of this project is to modify the catalyst developed during the Phase I effort in order to enhance its commercial viability. Enhancing the commercial viability will involve increasing the reactivity of the catalyst and eliminating platinum metals from the formulation. Enhancing the reactivity will allow the catalyst to operate at higher space velocities. Eliminating platinum metals from the formulation will greatly reduce the cost of the catalyst. Successful completion of this effort will result in a simple, low cost technology for control of NOx emissions from natural gas fired power plants without NH3 slip.Potential Commercial Applications include the control of NOx emissions from natural gas fired power plants. Other commercial applications include controlling NOx emissions from semiconductor manufacturing, fine and specialty chemical manufacturing and nitric acid manufacturing processes.

这个小型企业创新研究(SBIR)第二阶段项目包括开发一种催化剂，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NOx排放。在第一阶段的工作中，Guild Associates开发了一种使用NH3控制NOx排放的环境催化剂。在过量(约20-33%)NH3存在的情况下，催化剂能够实现大于95%的NOx脱除，而不会发生NH3滑移。由于催化剂能够同时将多余的NH3还原为N_2和H_2O，因此避免了NH_3滑移。该项目的目标是对第一阶段工作期间开发的催化剂进行改进，以提高其商业可行性。提高商业可行性将包括增加催化剂的反应性，并从配方中消除铂金属。提高反应性将允许催化剂在更高的空间速度下运行。从配方中去除铂金属将大大降低催化剂的成本。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NOx排放，而不会出现NH3滑移。潜在的商业应用包括控制天然气发电厂的NOx排放。其他商业应用包括控制半导体制造、精细和特种化学品制造以及硝酸制造过程中的NOx排放。
