摘要

含油污泥成分复杂、性质变化大、有毒物质含量高，可采用热解技术实现减容无害化处罪。基于热重-红外联用分析仪(TG-FTIR)研究了某含油污泥在N2/CO2气氛下的热解特性。结果表明:含油污泥热解过程主要分为低沸点烃类物质(300~500 ℃)的析出、无机碳酸盐(500~800 ℃)以及重质油等长链稳定有机大分子(900~1 100 ℃)的分解3个阶段；利用Coats-Redfern方法

求得含油污泥主要热解阶段的动力学参数

发现高温段的活化能高于中、低温段；N2/CO2气氛对中、低温段热解过程影响不大

但是在CO2气氛下高温段的活化能明显增加；热解产物FTIR分析得出其析出气体主要以CO2、CO以及CH4等轻质气体为主；在高温段

有大量的甲基化合物析出

且CO2气氛对其生成有明显的促进作用。
