Multi-scale reaction kinetic characteristics of waste tire pyrolysis

Cryogenic Center, Hangzhou City University, Hangzhou 310015, China

摘要

摘要: 在众多废轮胎处理方法中，热解法因其广泛的适用性、高效的效益以及较低的环境污染等显著优势，已成为当前的研究热点。利用热重分析技术，探究了不同升温速率对废轮胎的热解特性的影响，并在整体反应、失重阶段及Fraser-Suzuki解卷积三重尺度上，对废轮胎热解过程的反应动力学行为进行了系统分析。对比研究表明：Fraser-Suzuki函数凭借其非对称峰形拟合能力，在描述废轮胎热解这一复杂连续反应过程的动力学特性方面表现出更优的适用性。该函数成功地将废轮胎热解过程解卷积为添加剂、天然橡胶、合成橡胶及高温残余反应物4个伪组分的反应，其对应的平均活化能分别为118.21，202.60，231.98，251.97 kJ/mol。该研究可以为废轮胎热解工艺的温度分区调控及反应器优化设计提供关键理论依据。

Abstract: Among various waste tire treatment methods， pyrolysis has become a major research focus due to its significant advantages， including broad applicability， high resource recovery efficiency， and low environmental pollution. In this study， thermogravimetric analysis was employed to investigate the influence of different heating rates on the pyrolysis characteristics of waste tires. The reaction kinetics were systematically analyzed across three distinct scales： the overall reaction， the weight-loss stages， and the Fraser-Suzuki deconvolution. Comparative studies demonstrated that the Fraser-Suzuki function， with its asymmetric peak-fitting capability， exhibited superior performance in describing the kinetic characteristics of this complex and continuous reaction process during waste tire pyrolysis. Specifically， this function successfully deconvoluted the overall pyrolysis into four pseudo-component reactions， corresponding to additives， natural rubber， synthetic rubber， and high-temperature residual reactants. Their corresponding average activation energies were determined to be 118.21， 202.60， 231.98， 251.97 kJ/mol. This study provides important theoretical support for temperature-zone control and reactor design optimization in waste tire pyrolysis technologies.
