项目摘要

Due to the environmental and health-related hazards of airborne VOC emissions, Federal regulations will require improved VOC control technologies. Photocatalytic oxidation using UV illuminated titania catalysts has demonstrated the capability of destroying a wide range of organics, in particular halogenated compounds. Many bench scale reactor designs have been tested and show promise in some applications but are characterized by relatively poor light utilization and limited air treatment capacities. The proposed reactor design, which incorporates a suspended catalyst reactor combined with a ceramic filtration system for catalyst recycle, is very easily scaleable to high flow rates found in many VOC applications. The reactor design is a simple plug flow reactor in which suspended titania catalyst is periodically illuminated in the presence of VOC contaminated air. The suspended titania particulates are filtered using chemically durable, high efficiency, backpulsable ceramic filters which have a very high packing density. The resulting systems are very compact and allow the recycle of high activity suspended catalysts back to the photocatalytic reactor.
由于空气中挥发性有机化合物排放对环境和健康的危害,联邦法规将要求改进挥发性有机化合物控制技术。使用UV照射的二氧化钛催化剂的光催化氧化已经证明了破坏宽范围的有机物,特别是卤代化合物的能力。许多实验室规模的反应器设计已经过测试,并在某些应用中显示出希望,但其特征在于相对较差的光利用率和有限的空气处理能力。所提出的反应器设计,其结合了悬浮催化剂反应器与陶瓷过滤系统的催化剂再循环,是非常容易扩展到高流速在许多VOC应用。反应器设计是简单的活塞流反应器,其中悬浮的二氧化钛催化剂在VOC污染的空气存在下被周期性地照射。悬浮的二氧化钛颗粒使用化学耐用、高效、可反脉冲的陶瓷过滤器过滤,该陶瓷过滤器具有非常高的填充密度。所得到的系统非常紧凑,并且允许将高活性悬浮催化剂再循环回到光催化反应器。
