Abstract

Petroleum ASPHALTENE is the heaviest portion of oil fractions. ASPHALTENEs are defined as materials insoluble in aliphatic hydrocarbon solvents (n-pentane or n-heptane) and can cause coking or plugging difficulties in refineries and transportation lines. Therefore the structural characteristics and AROMATICITY of ASPHALTENEs are important to refiners for determining the operating parameters of the process units for deep conversion processes STRUCTURAL CHARACTERIZATION studies have been carried out on ASPHALTENEs extracted from three Iranian CRUDE OILs. The AROMATICITY and crystallite parameters as well as the layer distance between aromatic sheets, the distance between the saturated portions,the average diameter of aromatic sheets and the number of aromatic sheets in a stacked cluster of each sample have been estimated from X-RAY DIFFRACTION. Relation between the ASPHALTENEs AROMATICITY parameter and hydrocarbon distribution GC-mass chromatogram of CRUDE OILs has been investigated. Increasing in AROMATICITY parameter is proportional to the large molecular size of hydrocarbons content.
