Characterization Of Shale Oil By Spectroscopic And Chromatographic Techniques

01.Mar.2020

​

Abstract

Spectroscopic and chromatographic techniques were used to investigate the composition and chemical structure of the extracted shale oils. The shale oils were extracted from two Jordanian oil

shale fields using autoclave devise and fluid solvents at sub- and supercritical conditions. The analyses show that the variation of sub-and supercritical extraction conditions, particle size, solvent

type and shale field has a slight effect on the composition and chemical structure of the produce oil. Ultraviolet visible (UV-vis) spectra show two clear signals in the ranges of 210-235 nm and 275-

280 nm. The first could be attributed to benzenic compounds and the other one to naphthenic compounds. The 1 HNMR results indicate that the protons of methyl and methylene represent a high

proportion of the hydrogen (75-85%) in most shale oil samples. GC analysis shows that the oil samples contain n- alkane (n-C

25) with a high predominant proportion. FT-IR results also support

these findings. ​
