摘要

目前,废弃物处置在世界各地都得到了广泛的关注。由城市固体废物(MSW)制造的固体回收燃料(SRF)具有高热值的特性。本文利用热重-红外联用(TG-FTIR)和分布式活化能模型(DAEM)来研究从垃圾焚烧电厂获得的SRF及其分类组成的热解特性。通过比较升温速率和反应气流量的影响,确定了最佳反应工况。同时研究了SRF及其各组分在热解过程中的气态产物与官能团归属。此外,本文还提出了一种利用直接搜索法获得DAEM方程参数的方法,并给出了能够描述SRF热解过程中气体产物的DAEM方程,模型的预测结果与实验结果一致。研究获得的SRF热解动力学参数将为后续的理论建模提供基础。

Abstract

Currently, waste disposal has been highlighted strategically all over the world. Solid recovered fuel (SRF) with a high calorific value is manufactured from municipal solid waste (MSW). Thermogravimetric Fourier transform infrared spectroscopy (TG-FTIR) and distributed activation energy model (DAEM) were utilized to study the pyrolysis of the individual components and their mixture (i.e. SRF), which were obtained from a MSW incineration power plant. The best operating conditions were defined by comparing the effect of heating rates and flow rates of sweep gas. The gaseous products and functional groups in the pyrolysis of each component and their mixture were researched. Additionally, a direct search method was presented to obtain the DAEM kinetic parameters. DAEM equations for volatile products were given to describe pyrolysis of SRF. The model prediction results are consistent with the experimental results. The kinetic data will provide a basis for gas composition regulation from theoretical modeling.
