摘要： 挥发性有机物（VOCs）对大气污染和人体健康有着直接的影响，因此对其进行有效的处理是十分必要的。本文介绍了微波诱导金属放电作为一种高效、副产品附加值高的降解高浓度甲苯的方法。研究了金属种类（Fe、Cu、Ni、Zn）和含量对放电强度的影响。在最佳排放条件下，甲苯的降解率可达79.76%。此外，还将放电法与传统的700℃、900℃、1100℃热分解法进行了比较，微波诱导金属放电法产生的甲苯气相和液相裂解产物与900℃热分解法所得的产物基本相似，但是，固相放电产物为石墨化良好的纳米颗粒，而热分解产物为非晶态微粒。这项工作为降解高浓度VOCs提供了一种有效、灵活的方法，也为生物质焦油裂解和其它有机污染物的去除提供了应用参考。

Abstract: The effective treatment of volatile organic compounds (VOCs) is essential because of their direct effects on air pollution and human health. This paper introduces microwave-induced metal discharge as a highly effective and byproduct value-added approach to degrade high-concentration toluene as a model VOC. The effect of the factors that influence the discharge intensity, including the metal type (Fe, Cu, Ni, Zn) and amount, was investigated. Degradation efficiency of toluene can reach 79.76% under optimal discharge condition. In addition, the discharge method was compared with traditional thermal destruction at 700 °C, 900 °C and 1100 °C. The gaseous and liquid cracking products of toluene produced by the microwave-induced metal discharge method were almost similar to those obtained under thermal destruction at 900 °C; however, the solid-phase discharge products were nanoparticles that demonstrated good graphitization, while the thermal destruction products were amorphous microparticles. This work offers an effective and flexible way to degrade high-concentration VOCs and also provides an application reference for biomass tar cracking and removal of other organic pollutants.
