1702166 PI: Locke, Bruce The major aim of the proposed work is to experimentally investigate the sustainable chemical production of nitrate and hydrogen peroxide using a gas-liquid non-thermal plasma reactor. This project also seeks to advance the understanding of the design principles of gas-liquid plasma reactors for chemical synthesis. The underlying theme of this proposal is that providing farmers a way to produce nitrogen fertilizer and hydrogen peroxide pesticide locally from sustainable resources, e.g., water, air, and solar energy, in a green chemical process, is an ideal approach to both reducing the environmental impact of fertilizer production and improving the productivity and profit margin of farmers. This project will advance sustainability in chemical reaction engineering through reduction in utilization of petroleum feedstocks for fertilizer and pesticide production. The proposed research aims to develop a detailed analysis of how non-thermal plasma reactors can be utilized to form nitrate and other species. In the plasma reactor the plasma discharge channels form on, and propagate along, the interface between a flowing gas and a flowing liquid. The reactor design principles to be developed include determination of how plasma properties interact with reactor characteristics and electrical conditions to facilitate synthetic chemical reactions involving nitrogen oxides. The project has three specific aims directed to three major hypotheses. The first specific aim involves the analysis of the chemical reaction mechanisms, and the major hypothesis is that the primary reaction pathway for nitrate formation is through hydroxyl radical reactions. The second specific aim deals with the analysis of the plasma properties and power supply characteristics, and determination of how these properties interact and affect the chemical reaction pathways. The major hypothesis is that nitrate formation efficiency can be controlled by variation of the plasma temperature, electron density, and input power characteristics (pulse power, voltage, frequency). The third specific aim deals with the analysis and development of novel chemical reactor design features for improved performance. The major hypothesis is that modifications of the internal geometry of the gas-liquid plasma reactor (including channel size and nozzle diameter), which affect the surface area, gas and liquid residence times, and plasma contacting, can affect the formation of nitrate via effects on formation of key reactive species including hydroxyl radicals. Outreach activities through the Challenger Center of the FAMU-FSU College of Engineering are proposed and will include presentations and learning modules about plasma applications and topics related to green chemical synthesis and agriculture.

1702166 PI：洛克，布鲁斯拟议的工作的主要目的是实验研究硝酸盐和过氧化氢的可持续化学生产使用气-液非热等离子体反应器。 该项目还旨在促进对用于化学合成的气液等离子体反应器的设计原理的理解。这项建议的基本主题是为农民提供一种利用可持续资源在当地生产氮肥和过氧化氢农药的方法，在绿色化学过程中，水、空气和太阳能是减少肥料生产对环境影响和提高农民生产力和利润率的理想方法。该项目将通过减少用于化肥和农药生产的石油原料的使用，促进化学反应工程的可持续性。拟议的研究旨在详细分析如何利用非热等离子体反应器形成硝酸盐和其他物种。在等离子体反应器中，等离子体放电通道形成在流动气体和流动液体之间的界面上，并沿着该界面传播。反应器设计原则包括确定等离子体特性如何与反应器特性和电气条件相互作用，以促进涉及氮氧化物的合成化学反应。该项目针对三个主要假设有三个具体目标。第一个具体目标涉及化学反应机制的分析，主要假设是硝酸盐形成的主要反应途径是通过羟基自由基反应。 第二个具体目标是分析等离子体特性和电源特性，并确定这些特性如何相互作用和影响化学反应途径。 主要假设是硝酸盐的形成效率可以通过等离子体温度、电子密度和输入功率特性（脉冲功率、电压、频率）的变化来控制。第三个具体目标是分析和开发新的化学反应器设计特征，以提高性能。 主要的假设是气-液等离子体反应器的内部几何形状（包括通道尺寸和喷嘴直径）的修改（其影响表面积、气体和液体停留时间以及等离子体接触）可以通过对包括羟基自由基的关键反应性物种的形成的影响来影响硝酸盐的形成。建议通过FAMU-FSU工程学院的挑战者中心开展外联活动，其中将包括关于等离子体应用以及与绿色化学合成和农业有关的专题的介绍和学习模块。
