*** 96-61449 Rossin This project investigates the development of a novel catalyst to control the emissions of volatile nitrogen-containing compounds (VNC's) without the generation of chemical NOx. VNC's are both hazardous and odorous, and therefore, their emissions must be controlled. Current technologies used to control VNC emissions result in the generation of significant amounts of NOx due to the atomic nitrogen associated with the VNC. The release of NOx into the atmosphere is a significant problem, since it has been linked to both smog and acid rain. Catalytic oxidation is a technology well suited for controlling vapor phase emissions. However, no catalyst is commercially available which is capable of destroying VNC's without the formation of NOx. A novel catalyst was recently identified which has demonstrated the ability to destroy hydrogen cyanide without forming NOx over a wide range of process conditions. The objective of this Phase I proposal is to modify this novel catalyst in order to enhance its reactivity and minimize its N20 selectivity. To meet this objective, developmental catalysts will be evaluated for nitrogen-product selectivity and performance stability over a range of process conditions. Technologies capable of economically controlling the release of VNC's without the formation of NOx are currently unavailable. Should the novel catalyst prove successful, economical pollution abatement systems may be designed around the catalyst to meet the needs of a wide variety of applications which include controlling plant fugitive emissions and fume abatement. ***

*96-61449松香本项目研究开发一种新型催化剂，在不产生化学氮氧化物的情况下控制挥发性含氮化合物(VNC)的排放。VNC既危险又有气味，因此，它们的排放必须得到控制。目前用于控制VNC排放的技术由于与VNC相关的原子氮而导致大量NOx的产生。氮氧化物向大气中的释放是一个严重的问题，因为它与烟雾和酸雨都有关。催化氧化是一种非常适合控制气相排放的技术。然而，商业上没有一种催化剂能够在不形成NOx的情况下摧毁VNC。最近发现了一种新型催化剂，该催化剂在广泛的工艺条件下能够在不生成NOx的情况下破坏氰化氢。第一阶段方案的目的是对这种新型催化剂进行改性，以提高其反应活性，并将其N20选择性降至最低。为了实现这一目标，将在一系列工艺条件下评估开发的催化剂的氮产物选择性和性能稳定性。目前还没有能够在不形成NOx的情况下经济地控制VNC排放的技术。如果新型催化剂被证明是成功的，可以围绕催化剂设计经济的污染缓解系统，以满足广泛的应用需求，包括控制工厂逃逸排放和减少油烟排放。***
