SBIR Phase II: Photocatalytically Active Filters for Volatile Organic Compounds (VOC) Removal from Gas Streams

* 9801248 Zamansky该SBIR项目第二阶段继续研究利用光催化反应器过滤器（PRF）有效去除气流中的VOC（挥发性有机化合物）和PM（颗粒物质），然后再将其排放到大气中。 在第一阶段研究中，在小型催化反应器中进行了经济分析和测试。 第一阶段证实，脉冲重复频率系统在经济和技术上均是可行的，并可达致高效率的挥发性有机化合物控制。 第二阶段计划的总体目标是开发信息，并知道如何将技术推向第三阶段的全面示范。 第二阶段计划将在两年的时间内进行，并将最终发展一个概念性的全尺寸设计。 第一年第二阶段的技术目标将是设计和建造研究原型，制备和表征催化剂，并开始测试程序。 选择了两个潜在的应用程序进行优化：从纸浆和纸张和干洗行业的VOC/PM排放的去除。 第二年的目标将是完成测试计划和工程设计以及经济研究。 第二阶段将证明，与商用挥发性有机化合物控制技术相比，以环保的方式有效去除细颗粒物，可以实现90%以上的挥发性有机化合物控制水平，成本显著降低。 PRF系统的潜在应用包括化学制造、有机化学工艺、半导体制造、石油精炼、燃烧系统、纸浆和造纸工业、干洗、从工业废水沃茨中汽提的VOC的处理等。所有这些都具有含有氯化或非氯化VOC的废气流。 该工艺具有广泛应用于空气和工业气体中VOC和颗粒物去除的潜力。 ***

*** 9801248 Zamansky This Phase II SBIR project continues research on utilizing the Photo-catalytic Reactor-Filters (PRF) for effective VOC (volatile organic compounds) and PM (particulate material) removal from gas streams before discharging them to the atmosphere. An economic analysis and testing in a small catalytic reactor were performed in the Phase I study. Phase I confirmed that the PRF system is economically and technically feasible and can achieve high efficiency VOC control. The overall objective of the Phase II program is to develop information and know how to move the technology to the full scale demonstration, Phase III. The Phase II program will be conducted over a two year period and will culminate in development of a conceptual full scale design. The first year Phase II technical goal will be to design and construct a research prototype, prepare and characterize the catalysts, and start the test program. Two potential applications were selected for optimization: removal of VOC/PM emissions from pulp and paper and dry cleaning industries. The second year goal will be to complete the test program and engineering design and economic studies. Phase II will demonstrate that above 90% VOC control levels can be achieved with effective removal of fine particles in an environmentally safe manner for sigificantly lower cost when compared to commercial VOC control technologies. Potential applications of' the PRF system include chemical manufacturing, organic chemicals processes, semi-conductor manufacturing, petroleum refining, combustion systems, pulp and paper industry, dry cleaning, treatment of VOCs stripped from industrial waste waters, etc., all of which have off-gas streams that contain chlorinated or non-chlorinated VOCs. The process has the potential to be widely used for VOC and particulate removal from air and industrial gases. ***
