Abstract
The shale oil from Yaojie oil shale (YSO), Gansu Province, was subjected to acid-base separation to obtain acidic, basic and neutral fractions. The three fractions were characterized by gas chromatography–mass spectrometry (GC– MS). The GC−MS analysis showed that the neutral fraction (84.39wt %) contained C8~C33 normal alkanes, C8~C27 alkenes, benzene, naphthalene, phenanthrene (or paranaphalene) and other constitutions containing more than one benzene rings; the acid fraction (2.44wt%) mainly contained phenol, naphthol and indenol. Diphenol series were also identified in the acid fraction; the basic component (3.41wt%) consist of phenylamine, derivatives of pyridine, quinoline series. In this paper, the composition of YSO was widely investigated at the molecular level. The chemical composition of YSO provides important theoretical data for technology development.
