SBIR Phase I: Development of a Volatile Nitrogen-Containing Compound Pollution

*** 96-61449罗辛本项目研究一种新型催化剂的开发，以控制挥发性含氮化合物（VNC）的排放，而不产生化学NOx。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排放的技术导致产生大量的氮氧化物，因为与VNC相关的原子氮。氮氧化物释放到大气中是一个重大问题，因为它与烟雾和酸雨有关。催化氧化是一种非常适合控制气相排放的技术。然而，没有一种催化剂是商业上可用的，能够破坏VNC而不形成氮氧化物。最近发现了一种新型催化剂，它在各种工艺条件下都能破坏氰化氢而不形成氮氧化物。第一阶段的目标是对这种新型催化剂进行改性，以提高其反应活性并减少其对N20的选择性。为了实现这一目标，将在一系列工艺条件下评估开发催化剂的氮产物选择性和性能稳定性。能够经济地控制VNC的释放而不形成NOx的技术目前是不可用的。如果新型催化剂被证明是成功的，经济的污染减排系统可以围绕催化剂设计，以满足各种应用的需要，包括控制工厂逸散性排放和烟雾减排。＊＊＊

*** 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. ***
