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

* 96-61449 Rossin 该项目研究开发一种新型催化剂，以控制挥发性含氮化合物（VNC）的排放，而不会产生化学NOx。VNC既危险又有气味，因此必须控制其排放。用于控制VNC排放的当前技术由于与VNC相关的原子氮而导致产生显著量的NOx。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于控制气相排放的技术。然而，没有能够在不形成NOx的情况下破坏VNC的市售催化剂。最近鉴定了一种新型催化剂，其已经证明了在宽范围的工艺条件下破坏氰化氢而不形成NOx的能力。该阶段I提案的目的是改性这种新型催化剂以增强其反应性并使其N2 O选择性最小化。为了实现这一目标，将在一系列工艺条件下对开发催化剂的氮产品选择性和性能稳定性进行评价。 能够经济地控制VNC’s的释放而不形成NOx的技术目前是不可用的。 如果新的催化剂被证明是成功的，则可以围绕该催化剂设计经济的污染消除系统，以满足包括控制工厂无组织排放和烟雾消除的各种应用的需要。 ***

*** 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. ***
