【摘要】 综述了有机废弃物热解过程中主要应用的分析方法,首先介绍热分析法的种类和影响因素,重点归纳了热重分析法的应用,明确了升温速率、热解气氛、驻留温度和驻留时间等是影响热解的重要因素;其次对热解动力学和热解热力学进行总结,对比了无模型法(FWO、KAS、Starink法)和有模型法(C-R法);然后对热重-傅里叶红外联用分析(TG-FTIR)、热重-质谱联用分析(TG-MS)、热解-质谱色谱联用分析(Py-GC/MS) 3种热解气体逸出分析方法进行对比总结;最后从工业生产、研究热解机理和热解产物控制的角度提出目前有机废弃物热解分析技术的问题以及对未来热解技术发展的展望。
【Abstract】 In the paper, the main analytical methods used in the pyrolysis process of organic waste were reviewed. The types and influencing factors of thermal analysis were introduced, and the application of thermogravimetric analysis was focused. It was concluded that temperature rise rate, pyrolysis atmosphere, residence temperature, and residence time were the major factors for controlling the pyrolysis process. The pyrolysis kinetics and thermodynamics were summarized, and the model-free methods(FWO’s, KAS’, and Starink’s methods) and model-free methods(C-R method) was compared. The analysis methods for pyrolysis gas including thermogravimetric Fourier-infrared spectroscopic analysis, thermogravimetric mass spectrometric analysis, and pyrolytic-mass spectrometry chromatographic analysis were compared and summarized. Finally, the current problems of organic waste pyrolysis analysis technology and the prospect of future pyrolysis technology development were put forward from the perspectives of industrial production, pyrolysis mechanism, and pyrolysis product control.
