Characterization of Petroleum Crude Oils by Fourier Transform Infrared (FT-IR) and Gas Chromatography-Mass Spectrometerys

Abstract

We attempted to analyze light, medium, and heavy petroleum crude oils by Fourier transform infrared (FT-IR) and gas chromatographic mass spectrometry (GC-MS) so as to identify and quantify the various hydrocarbon group types and heteroatom-containing hydrocarbons. The results inferred that the crude oils studied have quite similar individual hydrocarbons but differ in hydrocarbon group types i.e. paraffinic, olefinic, naphthenic, and aromatic group types and carbon range products distributions. The RCP-I is dominated by C11-C13, while RCN-II and RCA-III by C5-C10 range hydrocarbons.
