摘要
为了使废轮胎达到资源化利用，在对废轮胎回转窑中试热解油进行品质分析的前提下对其应用前景进行了研究。通过与各种商用石油衍生油品的比较，认为当热解油产量较低时，可以将其整体作为重柴油使用：而当产量较高时，按照不同馏分加工利用可实现其价值的提升。热解石脑油馏分的BTX（苯、甲苯、二甲苯）含量达40％～50％，可以通过加氢预处理、溶剂抽提和精馏分离回收其中的轻质芳烃。
For recycling the used tires, properties of pyrolytic oil from pyrolysis of used tires in pilot-scale rotary kiln were analyzed. With complete knowledge of the composition and properties of the pyrolytic oil, estimation of its application was possible. By comparison with industrially petroleum fuel, it＇s considered that pyrolytic oil can be used as diesel oil when the output is low; and when enough, it can be fraetionated to optimize the value. The content of BTX in the naphtha fraction of the pyrolytic oil amount to 40% - 50% which can be reclaimed light aromatic hydrocarbon by hydrogenation pretreated, solvent elution and rectification.
