摘要：

以工业试验装置生产的废轮胎热解油为研究对象，对废轮胎热解油中的烃类和非烃类化合物的分布进行研究。结果表明，热解油中的芳烃、烯烃含量高，饱和烃含量低，属于高硫高氮高酸油。热解油中硫主要以噻吩形式存在，总硫含量及噻吩硫含量随着馏分沸点的升高而增大；硫醇硫主要集中于小于300 ℃的馏分中；硫醚硫主要集中于小于150 ℃和大于500 ℃的馏分中。热解油中的总氮含量随着馏分沸点的升高而增大，碱性氮含量占1/3，非碱性氮占2/3。热解油中酸性组分主要集中于200～400 ℃的馏分中。

Abstract:

The distributions of hydrocarbon and non-hydrocarbon compounds of the pyrolysis oil generated from an industrial test facility were analyzed. The results showed that aromatics content and olefins content in the pyrolysis oil were high，and saturated hydrocarbons content was low，and the pyrolysis oil had high sulfur content，high nitrogen content and high acid value. The sulfur content increased with increasing boiling point of the pyrolysis oil fraction. Sulfur compounds were mainly thiophenes. Mercaptan sulfur mainly existed in the fractions with boiling point lower than 300℃. Sulfide sulfur mainly existed in the fractions with boiling point lower than 150℃ and higher than 500℃. With increasing boiling point，the total nitrogen content increased. Basic nitrogen content and non-basic nitrogen content were 1/3 and 2/3，respectively. Acidic compounds in the pyrolysis oil were mainly concentrated in the fractions with boiling point 200—400℃.
