Safe disposal of hazardous waste is becoming generally more important as industrial production increases. The pyrolysis characteristics and gas evolution of mixtures of several wastes are discussed in this paper. Experiments are described for various heating rates, particle sizes and final temperatures using thermogravimetric analysis (TGA) and a Fourier transform infrared spectrometer. The results indicate that there are three stages in the pyrolysis process. The composition of evolved gas includes carbon monoxide, carbon dioxide, ammonia, methane, nitric oxide, hydrocyanic acid and a number of other light alkanes. Gas evolution temperatures and gas generation rates were significantly influenced by the factors identified.
随着工业生产的增加,危险废物的安全处置变得越来越重要。本文讨论了几种废物混合物的热解特性和气体演变。实验采用热重分析(TGA)和傅里叶变换红外光谱仪,研究了不同加热速率、粒度和最终温度下的情况。结果表明,热解过程有三个阶段。所产生气体的成分包括一氧化碳、二氧化碳、氨、甲烷、一氧化氮、氰化氢和许多其他轻烷烃。气体逸出温度和气体生成速率受所确定因素的显著影响。
