Distribution of vanadium and vanadyl porphyrins in petroleum distillates of different chemical types
Abstract 1. The greater part of atomic vanadium and vanadyl porphyrin molecules present in crude oils from all producing layers of the Samotlor deposit is concentrated in the petroleum resin, although the absolute concentration of V is maximum in asphaltene fractions. Vanadium atoms associate mainly with hetero-aromatic fragments of crude oil resin-asphalt substances. Up to 98% vanadium is contained in asphaltenes and almost all V atoms in petroleum fractions are contained in non-porphyric compounds. 2. Using Samotlor crude oils a clear is observed with: a) a reduction in overall vanadium concentration in all fractions, b) in the content of vanadyl porphyrins in malthene fractions, c) according to the paraffinicity of crude oils, particularly in relation to intensification of catagenic transformations with increasing depth and age of the surrounding deposits.
