I-Corps: Green chemical route to the small scale production of hydrogen peroxide

该项目旨在开发等离子体气液反应器，以生产化学消毒剂（例如，过氧化氢和羟基自由基）。美国国家科学基金会先前的支持提供了基本化学反应的知识，以及在小型实验室规模的反应器中形成活性物质（包括羟基自由基和过氧化氢）的机制，其中非热等离子体与液态水接触。研究小组发现，当气相中形成的等离子体接触流动的液膜或水滴气溶胶时，可以获得更高的效率，并利用它来开发反应器系统。 所开发的反应器系统非常简单、耐用和坚固。虽然它目前是相对较小的实验室规模，但我们希望可以解决规模扩大问题，以便该系统可以对小型加工厂的市场产生潜在影响，也许是需要便携性和低单位费用的个人使用。和化学氧化可以解决许多公共健康和环境问题，以及提高工业效率。小型高效气体-液体等离子体反应器可广泛用于各种这样的应用中。

This project seeks to develop plasma gas-liquid reactors to produce chemical disinfectants (e.g., hydrogen peroxide and hydroxyl radicals) through plasma formation. Previous support from NSF has provided knowledge of the basic chemical reactions and the mechanisms for the formation of reactive species including hydroxyl radicals and hydrogen peroxide in small laboratory scale reactors where non-thermal plasma contacts with liquid water. The research team has discovered that higher efficiencies can be obtained when plasma formed in the gas phase contacts a flowing liquid film or an aerosol of water droplets and used this to develop a reactor system. The reactor system developed is quite simple, durable, and robust. While it is currently of relatively small laboratory scale, we expect that the scale up can be addressed so that the system can have a potential impact on the market for small processing plants and perhaps personal use where portability and low unit expense are needed.The development of new technologies for disinfection, water cleaning, and chemical oxidation can address many public health and environmental problems as well as improve industrial efficiency.Small scale efficient gas-liquid plasma reactors may find wide use in a variety of such applications.
