摘　　要：通过对几种有害固体废物(废橡胶,废电路板,医疗废物,废油漆,污泥)的热解实验,考察了不同工况下有害固体废弃物热解焦油的特性。研究了不同工况下焦油产率的影响因素。物料特性、热解终温及加热方式,对有害固体废物热解焦油的产率有着重要的影响。在实验温度范围内,不同工况条件下,对热解焦油密度和热值进行了测定,热解焦油密度在0.75～0.95g/ml范围内,焦油热值在6.306～9.112kal/g之间,高于原始物料的热值。对不同工况下的热解焦油进行了族分分析,焦油中一般饱和烃和极性物的含量较高。The tar produced from pyrolysis of several hazardous wastes, including rubber, electric board, hospital wastes ,paints and sludge,was characterized.It was found that there are three factors-material properties, final pyrolysis temerature (FPT) and heat method, affect the pyrolytic tar productivity of hazardous solid waste at a high level. The tar productivity and its composition vary when any factor of them changes. The density of pyrolytic tar range from 0. 75g/ml to 0. 95g/ml,and the heat value of tar range from 6. 306kcal/g to 9. 112kcal/g, the heat values are all higher than their origin materials'. We have analyzed the content of pyrolytic tar, the aliphatic and aromatic in pyrolytic tar is high.
