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，通过等离子体形成产生化学消毒剂（如过氧化氢和羟基自由基）。NSF先前的支持提供了基本化学反应的知识，以及在非热等离子体与液态水接触的小型实验室规模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。研究小组发现，当气相形成的等离子体与流动的液体膜或水滴气溶胶接触时，可以获得更高的效率，并利用这一点开发了一个反应堆系统。所研制的反应器系统简单、耐用、坚固。虽然它目前是相对较小的实验室规模，但我们预计可以解决扩大规模的问题，以便该系统可以对小型加工厂的市场产生潜在影响，并且可能对需要便携性和低单位费用的个人使用产生潜在影响。消毒、水清洗和化学氧化新技术的发展可以解决许多公共卫生和环境问题，并提高工业效率。小型高效气液等离子体反应器可能在各种此类应用中得到广泛应用。

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.
