中文摘要：
利用热重分析法和实验室自行设计的静态热解炉对脱墨污泥的热解行为及热裂解特性进行了研究,探讨了不同升温速率对脱墨污泥热解反应特性的影响,并根据微分热重曲线建立了动力学模型,计算热解反应的动力学参数。结果表明,脱墨污泥的热失重过程可分为水分析出、挥发物质析出、固定碳燃尽和碳酸钙热分解4个阶段,其热解反应动力学为3个三级反应。从利用电子探针显微技术、气相色谱和傅里叶红外分析方法对热裂解产物进行表征的结果来看,造纸脱墨污泥具有很好的资源化综合利用前景。
英文摘要：
Pyrolysis characteristics of waste paper deinking sludge were studied by thermogravimetric analysis.The effects of different heating rates on the pyrolysis characteristics of the deinking sludge were investigated,and the dynamical model of this pyrolysis process was also established.The results showed that the dynamical model of this pyrolysis process could be expressed by three third-order parallel reactions,and the non-isothermal weight-loss process of the deinking sludge was composed of four stages,including dewater stage,volatile matter releasing stage,carbon burnout stage,and Calcium carbonate decomposition stage.In the paper,the deinking sludge was decomposed in the static pyrolysis furnace that was designed by our laboratory;its pyrolysis products were characterized by EPMA,GC and FT-IR.The results showed that the comprehensive utilization of deinking sludge was considerably feasible.
