Abstract
The crude oil residues are generally recognized to be composed of three major fractions: asphaltenes, resins, and oils. Methods for separation of heavy oils and residues have undergone several modifications since the development of USBM-API method. In recent years application of nuclear magnetic resonance (NMR) and infrared (IR) spectroscopic analyses to elucidate the chemical structure of petroleum residues and asphaltenes has grown considerably. In this paper, the results of separation and structural characterization of fractions from four Saudi Arabian Crude oil residues are reported.
