本文利用介质阻挡放电等离子体技术,对以煤和生物质为代表的固态可燃物液化反应机理进行研究,以期探索能源利用新途径。借助碰撞理论和Boltzman方程,对高能电子碰撞引发多种离解反应的速率常数进行数值模拟,计算结果和实验曲线对比,证明模型具有一定的适用性和可靠性。在一定的电子温度下,通过不同离解反应速率常数的对比,可以判断反应产生的活性粒子情况和反应的进程,为分析DBD等离子体固态可燃物液化反应机理和控制预报液化反应过程及产物成分提供理论依据。
In this paper, the dielectric barrier discharge plasma technology is used to study the liquefaction reaction mechanism of solid flammable materials, such as coal and biomass, in order to explore new ways of energy utilization. Based on the collision theory and the Boltzman equation, the rate constants of various dissociation reactions induced by high energy electron collisions are numerically simulated. The calculated results are in good agreement with the experimental curves, which proves that the model has some applicability and reliability. At certain electron temperature, through the comparison of different dissociation reaction rate constants, we can determine the reactive particles and reaction process. In order to analyze the liquefaction reaction mechanism of solid DBD plasma combustibles and predict the liquefaction reaction and product composition Theoretical basis.
