摘要: 以轮胎顶线油为研究对象,对其烃类及非烃类物质分布进行研究,通过对其进行精确切割,采用微库仑仪、GC-MS手段获得其各窄馏分的元素和烃类组成及含氯化合物的主要成分和氯含量分布,并采用碱洗方法对轮胎顶线油进行脱氯预处理,通过正交试验考察了反应温度、反应时间、NaOH溶液与轮胎顶线油体积比对脱氯效果的影响。结果表明:轮胎顶线油中各窄馏分的饱和烃、氯含量分布随馏程温度升高呈降低的趋势,不饱和烃含量分布较均匀,芳烃含量随馏程温度升高逐渐增加;通过正交试验得到的最优碱洗脱氯工艺条件为反应温度100 ℃、反应时间4 h、NaOH溶液与轮胎顶线油体积比1.5,该条件下的脱氯率为59.70%。

Abstract: The distributions of hydrocarbon and non-hydrocarbon compounds as well as the method of dechlorination pretreatment of the tire top line oil were studied. The tire top line oil was accurately cut into 10 narrow fractions, then the elements, hydrocarbons, the main chloric components and the chlorine distributions in each narrow fraction were investigated by micro coulometry and GC-MS analysis. Alkali wash method was used for dechlorination pretreatment of the top line oil. The influence of reaction temperature, reaction time and NaOH solution to tire top line oil volume ratio was tested by orthogonal test. The results show that saturated hydrocarbon and chlorine content decreases along with the temperature rise of distillation range, while aromatics content decreases. The distribution of unsaturated hydrocarbon content is more uniform. The dechlorination rate is 59.70% at the optimized conditions: reaction temperature of 100 ℃, reaction time of 4 h, NaOH solution to tire top line oil volume ratio of 1.5:1.
