Analysis of Synergistic Pyrolysis Characteristics of Torrefied Biomass and Waste Tires Based on Thermogravimetry
摘要
Abstract
To enhance the efficiency and reaction characteristics of the co-pyrolysis of biomass and organic solid waste,this study investigated the synergistic pyrolysis behavior of torrefied elm wood and waste tires using thermogravimetric analysis.The elm wood was torrefied at different temperatures(220,250,280 ℃)and mixed with waste tires in varying proportions(0％to 50％).Results indicated that the torrefaction pretreatment significantly improved the thermal stability and energy density of the biomass.The addition of waste tires further increased the initial pyrolysis temperature(up to 332 ℃)and the char yield.Incorporating a low proportion of tires(approximately 20％)notably reduced the activation energy,with a maximum decrease of 25.7％,demonstrating a promoting effect even under high torrefaction temperatures and tire addition levels.DTG curves revealed that waste tires attenuated the intensity of the biomass pyrolysis peak and induced a shift in the pyrolysis mechanism at higher temperatures,reflecting their thermal barrier and dilution effects.Building upon torrefaction pretreatment,controlling the waste tire blending ratio(within 20％)allows for the dual optimization of pyrolysis efficiency and product quality,providing a theoretical basis and technical reference for the synergistic thermal conversion of biomass and solid waste.关键词
