Abstract Identification of hydrocarbons in spent lubrication oil was carried out to establish it as valuable petrochemical feedstock. Spent oil, was collected mixed with water and fractionated under a controlled distillation set-up at 170 °C. Distillate and residue products were analyzed using GC-MS spectrometry method. Recovered products were predominantly aromatic compounds in the carbon range less than C20. Unsaturated compound were prevalent in the spent oil. Aliphatic and aromatic hydrocarbon compounds such as 2,5-Octadecadiynoic acid, methyl ester (C19H30O2), 2,9-Heptadecadiene-4,6diyn-8-ol (C17H24O), 5,8,11,14-Eicosatetraynoic acid, methyl ester (C21H34O2), 2-Hexadecanol (C13H34O), 1,3,5-trimethyl benzene (C9H12) and p-xylene (C8H10) were identified.

废润​​滑油的加氢蒸馏及产品表征

摘要 对废润滑油中的碳氢化合物进行了鉴定，以将其确定为有价值的石化原料。废油与水混合收集并在 170 °C 的受控蒸馏装置下分馏。使用 GC-MS 光谱法分析馏出物和残留产物。回收的产品主要是碳范围小于 C20 的芳族化合物。不饱和化合物普遍存在于废油中。脂肪族和芳香族烃化合物，例如 2,5-十八碳二炔酸甲酯 (C19H30O2)、2,9-十七碳二烯-4,6 二炔-8-醇 (C17H24O)、5,8,11,14-二十碳四炔酸甲酯(C21H34O2)、2-十六醇 (C13H34O)、1,3,5-三甲基苯 (C9H12) 和对二甲苯 (C8H10)。
