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.
