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.

Key words: thermal analysis method, waste organic matter, pyrolysis kinetics, pyrolysis thermodynamics, evolved gas analysis
