In this paper, the pyrolysis characteristics of six typical components in municipal solid waste (MSW) were investigated through a TG-FTIR combined technique and it was concluded that the main pyrolysis process of the biomass components (including food residues, sawdust and paper) occurred at 150-600°C. The main volatiles were multi-component gas including HO, CO, and CO. The main pyrolysis temperatures of three artificial products (PP, PVC and leather) was ranged from 200to 500°C. The wavelength of small molecule gases (CH, CO and CO) and the the chemical bonds (CO and CC) were observed in the infrared spectrum Based on the pyrolysis temperature interval and volatile constituent, a new "double-solution" process of pyrolysis and oxygen-enrichment decomposition MSW was designed. To achieve this process, a double-solution project was built for the direct treatment of MSW (10t/d). The complete setup of equipment and analysis of the byproducts has been reported in this paper to indicate the performance of this process. Energy balance and economic benefits were analysed for the process supporting. It was successfully demonstrated that the double-solution process was the environmentally friendly alternative method for MSW treatment in Chinese rural areas.
本文采用 TG-FTIR 联用技术研究了城市固体废物（MSW）中六种典型组分的热解特性，得出生物质组分（包括食物残渣、木屑和纸张）的主要热解过程发生在 150-600°C。主要挥发物是多组分气体，包括 HO、CO 和 CO。三种人工制品（PP、PVC 和皮革）的主要热解温度范围为 200 至 500°C。在红外光谱中观察到小分子气体（CH、CO 和 CO）的波长和化学键（CO 和 CC）。基于热解温度区间和挥发性成分，设计了一种新型的“双解”MSW 热解和富氧分解工艺。为了实现这一过程，为直接处理 MSW（10t/d）建立了一个双解项目。本文报道了设备的完整设置和副产物的分析，以表明该过程的性能。该过程支持的能量平衡和经济效益进行了分析。成功证明了双解工艺是中国农村地区处理城市固体废物的环保替代方法。
