摘要:
通过热重红外分析仪(TG-FTIR)研究垃圾衍生燃料(refuse derived fuel,RDF)在升温速率为10,℃/min、 20,℃/min、30,℃/min、40,℃/min、50,℃/min 及RDF 与褐煤在质量比为0∶10、3∶7、5∶5、7∶3、10∶0 时轻 质气体的析出特性,利用Coats-Redfern 法,求得热解动力学参数.研究发现,不同升温速率及不同质量配比时 RDF 热解过程主要分为3 个阶段:生物质组分热解(173~433,℃)、塑料类物质热解(402~566,℃)及无机碳酸盐 热解(大于650,℃).热解过程轻质气体CO2、CH4、CO 析出均表现为双峰特性;CO2 的释放集中在低温段 (200~300,℃)和高温段(600~800,℃),CO 的释放集中在低温段(300~400,℃)和高温段(600~800,℃),CH4 的 释放集中在中温段(300~600,℃).随着升温速率的增加,轻质气体CO2、CH4及CO 析出峰值浓度增加.RDF 与 褐煤共热解过程存在协同作用.
Abstract:
The pyrolysis gas characteristics of refuse derived fuel(RDF)at the heating rates of 10,℃/min, 20,℃/min,30,℃/min,40,℃/min,50,℃/min and at the mass ratios of 0∶10,3∶7,5∶5,7∶3,10∶0 with lignite are,respectively,studied by the infrared thermogravimetric analysis.The apparent kinetic parameters are obtained by using the Coats-Redfern method in the pyrolysis stage.The study finds that the pyrolysis process of RDF at different heating rates and different mass ratios can be divided into three stages:biomass components pyrolysis( 173—433,℃),plastic materials pyrolysis(402—566,℃)and inorganic carbonate pyrolysis(>650,℃).In the process of pyrolysis,light gases(CO2,CH4 and CO)reflect a bimodal characteristic.However,CO2 is released in the periods of low temperature(200—300,℃)and high temperature(600—800,℃).CO is released in the periods of low temperature(300—400,℃)and high temperature(600—800,℃),while CH4 is released in the period of middle temperature(300—600,℃).With the heating rate speeding up,the peak concentrations of the light gases CO2,CH4 and CO increase.There is a synergistic effect between the co-pyrolysis of RDF and lignite.
