Abstract :

Four Egyptian crude oils (Marine Shoukeir-22, Marine West Ashrafi, Arta-4 and Hana-3) of different API gravities ranging from 38.55 to 16.20 were fractionated into saturates, aromatics, resins and asphaltenes (SARA) through liquid column chromatography. Nickel (Ni) and Vanadium (V) contents were measured using atomic absorption spectroscopy. The physicochemical properties were studied for: (і) the four crude oils before fractionation and (іі) the technical fractions (gasoline, kerosene, gas oil, lubricating oil and vacuum residue over 370 oC) of Shoukeir-22 and Hana-3. It was clear that the resins and asphaltenes increase for heavy crude oils (Arta-4 and Hana-3). All crude oils have high contents of the technical fractions except that the content of the vacuum residue was little in Shoukeir-22 crude oil. The gasoline fraction of Shoukeir-22 and Hana-3 can be used as a charge stoke for the production of aviation or motor gasoline. The kerosene fraction of Shoukeir-22 is shown to be more suitable as a fuel for motor jets and for illumination.
