摘　　要：该文研究了废酸油渣样品中的正构烷烃、类异戊二烯、多环芳烃、萜烷和甾烷类化合物的指纹分布规律。结果表明,来源一致的废酸油渣样品的正构烷烃、类异戊二烯、萜烷类化合物和甾烷类化合物符合风化规律,而多环芳烃组分大多不符合风化规律,且部分多环芳烃诊断比值存在差异。为研究废酸油渣油指纹的变化规律,采用浓硫酸对市售润滑油进行磺化模拟实验。磺化模拟实验揭示了多环芳烃风化曲线和诊断比值的变化规律,浓硫酸的加入使得多环芳烃风化曲线发生明显变化,但仍有9个多环芳烃的诊断比值表现出较强的稳定性,这些诊断比值可用于酸性废矿物油的来源鉴别。The fingerprint distribution of n-alkanes,isoprenoids,polycyclic aromatic hydrocarbon,terpanes and steroids in waste acid oil residue was studied.The results showed that n-alkanes,isoprenoids,terpanes and steranes in the waste acid oil residue samples from the same source accord with the weathering law,but the polycyclic aromatic hydrocarbon components do not accord with the weathering law,a few of the PAHs were different.In order to study the variation of fingerprint of waste acid oil residue,the sulfonating simulation experiment of Lube oil was carried out with concentrated sulfuric acid.The sulfonating simulation experiment revealed the change rule of the polycyclic aromatic hydrocarbon weathering curve and the diagnostic ratio.The addition of concentrated sulfuric acid made the polycyclic aromatic hydrocarbon weathering curve change obviously,however,polycyclic aromatic hydrocarbon diagnostic ratios were stable and could be used to identify the source of acid waste mineral oil.
