中文摘要：

为了解不同热源作用下污泥的热解特性，实现污泥的资源化，采用TG—FFIR联用的分析方法对不同升温速率下污泥传统热解的失重特性和产物生成特性进行了研究，并与污泥微波热解对应的实验数据比较，探讨微波热解污泥的主要过程及特点．结果表明：微波热解的热重曲线与。100℃／min升温速率的热重曲线相似，与缓慢热解时的3个阶段相比发生一定的交错．碳氢化合物热解过程中的脱羧基作用产生CO2，烷烃热裂解产生CH4，而未挥发的水分、CO2与污泥中焦炭的反应是CO的主要来源．微波热解条件下，微波能强吸收物质活性炭对CO和H2的产生有很大的贡献．

英文摘要：

To obtain the pyrolysis characteristics of sewage sludge under different heat sources and achieve the resources of sludge, a study was carried out on the traditional pyrolysis characteristics and gas production of swage sludge at different heating rates by TG - FHR analysis. The feature and major process of microwave pyrolysis were investigated through data comparison. The results show that the TG curves of microwave pyrolysis and traditional pyrolysis at the heating rate of 100℃/min were similar, in which three periods of losing weight occur at the same time. FTIR analysis results indicate that decarboxylation of hydrocarbons produces CO2, alkane pyrolysis produces CH4, and the response of water, CO2 and coke is a major source of CO. Activated carbon used as microwave absorbing material plays a significant role in the production of CO and H2 in the process of microwave pyrolysis.
