Then quality upgrading scheme was explored in order to solve the high content of sulphur and nitrogen in pyrolytic oil, low flash point as well. Yields of pyrolysis of scrap tires in a pilot-scale rotary kiln under 550℃were firstly summarized. Then elemental composition and physiochemical properties were analyzed on both pyrolytic crude oil and its fractions. Based on these researches, the feasibility that pyrolytic oil is used as fuel was discussed. From FT-IR spectra the functional group compounds were generally acquainted, and by column chromatography analysis chemical compositions were clearly known. Then through GC analysis the absolute content of BTX in pyrolytic crude oil was defined.

本文首先考察了中试回转窑550℃下的废轮胎热解产率及热解原油的元素组成和理化特性，对其作为燃料使用的可行性进行了分析；通过实沸点蒸馏研究了轻质、中质馏分热解油的基本特性：红外分析得出了有代表性馏分热解油的大致官能团组成形式，对热解油的强芳香性和部分不饱和性有了整体了解；化学族组成分析进一步了解了热解油内在化学族组成和含量，对热解油的内在性质有了更为深入理解；气相色谱分析对热解油中富含的苯、甲苯和二甲苯进行绝对定量，为热解油提取BTX化工原料的经济性提供了参考。

Produce light oil film spray conditions normally finish normally does not produce a spray, such as user surface in cigarette packages are often in a layer on the surface of another polyolefin film, humidity and temperature in particular to certain conditions, when oil coating, the surface oil often very short gasficatic cause light fastness oil attachthemselves badnessand and above on the surface of polyolefin film appears with uniform small steam fog, in which case the contrary result in reducing or andgrainy of the goods.

产生光油薄膜雾化条件正常情况下，上光油一般不会产生雾化，例如用户在香烟盒表面往往在表面再覆一层聚烯烃薄膜后，湿度大、特别是气温高到一定条件时，当底油涂布后，面油往往因极短暂的气雾致使光油附着牢度不好，而覆在上光油表面的聚烯烃薄膜就会出现浓浓的均匀的雾状小蒸汽，这时反而降低或导致商品的肉质的变化。
