中文摘要：

为提高非平衡等离子体技术降解甲苯的能量利用效果，采用非平衡等离子体技术降解甲苯污染气体，在气体体积流量0．1m^3／h、甲苯质量浓度1g／m3等条件下，考察了变频高压交流电源下非平衡等离子体反应器的热量损失、电场强度、频率和功率等因素对甲苯降解率的影响，探讨了非平衡等离子体反应系统的电源匹配性问题，以求达到进一步优化反应系统的目的。实验结果发现，电源频率与甲苯的降解和能量利用并非简单的线性关系，而是存在一个最佳匹配点，即在频率150Hz时，整个电路消耗的无功功率最低，用于降解的有功功率较高，这为今后工业上等离子体技术的应用提供了基础参数。

英文摘要：

A series of experiments were performed for toluene removal using non-equilibrium plasma technology for enhancing the energy utility efficiency of toluene decomposition. In the experiment, we tested the loss amount of heat in non-equilibrium plasma reactor, and analyzed the effect of electric field strength, frequency, and power on removal efficiency of toluene under intermediate frequency high voltage of AC under the condition of flux of 0. 1 m3/h and toluene concentration of 1 g/m3. Moreover, we discussed the matching characteristic of power supply in the whole non-equilibrium plasma reaction system for further optimizing the whole system. The experimental results show that frequency of high voltage is not a single relationship with removal efficiency of toluene and energy utilization. The useless power is the lowest and available power is higher on frequency of 150 Hz for toluene removal. The experimental datas support plasma technology further improvement for industrial application.
