SBIR Phase I: Heterogeneous Catalytic Peroxidation of Environmental Contaminants

这个小企业创新研究（SBIR）第一阶段项目将开发一个连续的多相催化过氧化过程，用于破坏水中有机和无机多相污染物。以Fe （II）为均相催化剂的Fenton过氧化法广泛应用于工业废水中有机和无机污染物的氧化处理。这需要酸化、絮凝、沉淀法回收铁，通常仅限于“批处理”。均相过氧化物通常只能达到有机污染物的部分氧化，产生有机酸。该项目将开发一种高效的多相过氧化催化剂和反应器设计，用于使用过氧化氢作为氧化剂氧化有机物，这将促进有机污染物的更深层次氧化，简化工艺设计，减少功耗，提高氧化速率，特别是对羧酸等更难处理的有机污染物。将研究的环境污染物包括苯酚、甲基叔丁基醚（MTBE）、氰化物和甲苯。该项目的商业应用将在污染控制和修复方面。该项目将与一家主要的过氧化氢生产商和一家污染控制市场的主要供应商合作运行。该项目将为控制污染和清除环境污染物提供更有效的过程，从而造福社会。

This Small Business Innovation Research (SBIR) Phase I project will develop a continuous heterogeneous catalytic peroxidation process for destruction of aqueous organic and inorganic heterogeneous contaminants. Fenton peroxidation with Fe (II) as a homogeneous catalyst is used extensively for the oxidative treatment of organic and inorganic contaminants in industrial wastewater. This requires acidification, flocculation, iron recovery by precipitation, and is generally limited to "batch operations." Homogeneous peroxidation often achieves only partial oxidation of organic contaminants, yielding organic acids. This project will develop a highly effective heterogeneous peroxidation catalyst and reactor design for oxidation of organics using hydrogen peroxide as oxidant, which will facilitate deeper oxidation of organic contaminants, simplify process design, reduce power usage, and increase oxidation rates, especially for more refractory organic contaminants such as carboxylic acids. Environmental contaminants that will be studied include phenol, methyl-t-butyl ether (MTBE), cyanide and toluene.The commercial application of this project will be in pollution control and remediation. The project will be run in collaboration with a major hydrogen peroxide producer and a leading supplier to the pollution control market. The project will benefit society by providing more effective processes for control of pollution and cleanup of environmental contaminants.
