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

*** 9801248 Zamansky SBIR二期项目继续研究利用光催化反应器过滤器（PRF）在气体排放到大气之前有效地去除气流中的VOC（挥发性有机化合物）和PM（颗粒物质）。一期研究进行了经济分析和小型催化反应器试验。第一阶段证实了PRF系统在经济和技术上是可行的，可以实现高效的VOC控制。第二阶段项目的总体目标是开发信息并了解如何将技术转移到第三阶段的全面示范。第二阶段的项目将持续两年，最终将形成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构建一个研究原型，制备和表征催化剂，并启动测试程序。选择了两个潜在的应用进行优化：去除纸浆和造纸以及干洗行业的VOC/PM排放。第二年的目标是完成测试程序、工程设计和经济研究。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，成本显著降低，可达到90%以上的挥发性有机化合物控制水平。PRF系统的潜在应用包括化学制造、有机化学品加工、半导体制造、石油精炼、燃烧系统、纸浆和造纸工业、干洗、从工业废水中剥离的挥发性有机化合物的处理等，所有这些都有含有氯化或非氯化挥发性有机化合物的废气流。该工艺具有广泛应用于去除空气和工业气体中的挥发性有机化合物和颗粒的潜力。＊＊＊

*** 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. ***
