摘　　要：根据Bartle的方法,分析了平庄褐煤固体热载体快速热解和钢甑慢速热解焦油。发现快速热解焦油中苯不溶物、沥青烯含量较高;在焦油的油馏份内脂肪族亚馏份中的低碳烃含量较高,芳烃亚馏份中萘、二甲基萘含量较高。还根据加热方式探讨了快速热解焦油上述特性的原因。The tars produced from Pingzhuang lignite by rapid pyrolysis with solid heat carrier as well pyrolysis in steel retort have been analysed using method of Bartle. It was found that contents of benzene insoluble and asphaltene materials in tars from rapid pyrolysis are higher, the lower hydrocarbons in aliphatic subfraction and dimethyl naphthalene in aromatic subfraction are higher as well. The machnism of formation of rapid pyrolysis tar with above features has been discussed in terms of heating method.
