摘要

通过超临界醇解炼化油泥回收轻质生物油,实验表明340 ℃、60 min、油泥与乙醇质量比1∶2时油相收率最高（59.37%）,且饱和烃与芳香烃含量分别达到15.78%和16.58%。脂肪烃、环烷烃与萘、菲、芴是饱和烃与芳香烃的主要组分,但直链烃在卤素催化下,通过羟基化、羧基化和酯化反应生成脂肪酸脂。油泥中的硫以噻喃形态进入轻质油,但噻喃会在乙醇作用下开环磺化、磺酰缩合使硫转移至沥青质;氮则以吡啶形态进入轻质油,重质油中的氮则以氨基和酰胺形态存在。

Abstract

The light bio-oil was recovered by supercritical ethanol liquefaction of petrochemical sludge（PS） in this study. The results show that under 340 ℃, 60 min and PS/ethanol mass ratio 1∶2 conditions, the highest oil phase yield is 59.37% and the contents of saturates and aromatics are 15.78% and 16.58%, respectively. Aliphatic hydrocarbons, cycloalkanes, naphthalene, phenanthrene and fluorene are the main components of saturated hydrocarbons and aromatic hydrocarbons. Among them, linear hydrocarbons generat fatty acid lipids through hydroxylation, carboxylation and esterification under the catalysis of halogen. The sulfur in PS enters light oil in the form of thiophene, but sulfur can be transfer to asphaltenes by ring-opening sulfonation and sulfonyl condensation in the presence of ethanol. Nitrogen is transferred into light oil in pyridine form, while the nitrogen in the heavy oil is in the form of amines and amides.
