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

*9801248扎曼斯基这个二期SBIR项目继续研究利用光催化反应器-过滤器(PRF)有效地去除气流中的挥发性有机化合物(VOC)和颗粒物(PM)，然后将其排放到大气中。在第一阶段的研究中，在小型催化反应器中进行了经济分析和测试。一期工程证实PRF系统在经济上和技术上是可行的，可以实现高效的VOC控制。第二阶段计划的总体目标是开发信息，并知道如何将技术转移到全面示范阶段，即第三阶段。第二阶段计划将在两年内进行，最终将发展出一个概念性的全面设计。第一年第二阶段的技术目标将是设计和建造一个研究原型，准备和表征催化剂，并启动测试计划。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计划、工程设计和经济研究。第二阶段将证明，与商业VOC控制技术相比，通过以环境安全的方式有效去除细颗粒物，可以实现90%以上的VOC控制水平，从而显著降低成本。PRF系统的潜在应用包括化学制造、有机化工工艺、半导体制造、石油精炼、燃烧系统、纸浆和造纸工业、干洗、从工业废水中剥离的VOCs的处理等，所有这些行业的尾气都含有氯化或非氯化VOCs。该工艺有可能广泛应用于空气和工业气体中VOC和颗粒物的去除。***

*** 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. ***
