Novel Catalysts for Photocatalytic AIR Emissions Control

描述（由申请人提供）：超级基金计划旨在为废弃或不受控制的危险废物场地的危险物质提供补救措施。 健康问题要求这种清理工作迅速而彻底地进行。 然而，在今后几十年中，估计每年对这些地点进行补救的费用高达数十亿美元。 当务之急是开发更具成本效益的技术，以降低清理这些场所的社会成本。 拟议的研究项目的目标是证明一种新的补救技术的技术可行性。 有证据表明，与现有技术相比，这一技术可将补救费用降低一个数量级。 该研究计划包括开发新型光催化剂和吸附集成反应（AIR）技术的反应器系统，以高活性和非常高的选择性破坏氯化烃。 KSE公司已经开发了比常规二氧化钛光催化剂活性高几个数量级的光催化剂。 新的催化剂也更具选择性。 该研究项目将包括催化剂组合物的合成，挥发性有机化合物的代表性类别的动力学研究，反应器设计研究，以及建立概念可行性的设计分析。 预计将开发有效的补救技术，为超级基金场地的补救提供具有成本效益的工具。

DESCRIPTION (provided by applicant): The Superfund program is intended to provide remediation of hazardous substances at abandoned or uncontrolled hazardous waste sites. Health issues require that such clean ups proceed promptly and throughly. However, the cost of remediation of such sites is estimated at billions of dollars annually over the next several decades. It is imperative that more cost-effective technologies be developed to moderate the societal cost of clean up of these sites. The goal of the proposed research project is to demonstrate the technical feasibility of a new remediation technology, photocatalysis. Evidence suggests that this technology can reduce remediation costs by an order of magnitude over that of current technology. The research plan includes development of novel photocatalysts and reactor systems for an Adsorption-Integrated-Reaction (AIR) technology, to destroy chlorinated hydrocarbons with high activity and with very high selectivity. KSE, Inc. has developed photocatalysts which are orders of magnitude more active than conventional titania photocatalysts. The new catalysts are also more selective. The research project will consist of synthesis of catalyst compositions, kinetic studies on representative classes of volatile organic compounds, reactor design studies, and a design analysis which establishes feasibility of the concept. It is anticipated that an effective remediation technology will be developed, providing a cost-effective tool for remediation of Superfund sites.
