摘　　要：针对上海市天山污水处理厂的污泥样品,利用固定床反应器,结合现代分析仪器,如气相色谱仪(GC)、气相色谱-质谱联用仪(GC-MS)、扫描电子显微镜(SEM)等,对污泥热解残炭、油和不凝性气体的特性进行了分析研究。结果表明:不凝性气体H2、CO、CH4、CO2随反应温度的升高呈规律性变化。通过GC-MS联用分析技术,对热解油产物进行了定性分析,300℃时含氧化合物量最大,700℃时含氮化合物量最大。随着反应温度的提高,残炭表面空隙更加复杂化。Sewage sludge,produced by Shanghai Tianshan wastewater treatment plant,was pyrolysed in a quartz reactor.The results indicate that the non-condensable gas,mainly composed of H2、CO、CH4、CO2,changes regularly with the reaction temperature.The oil was analyzed by GC-MS,and a qualitative analysis was made.At 300℃,the oxygenated compounds are the biggest component,and at 700℃,the nitrogenated compounds are the main compounds.The surface pores of char particles change complicated as the temperature increases.
