摘要：

The distribution of nickel and vanadium in five fractions (saturated hydrocarbons, aromatic hydrocarbons, soft resin, hard resin, and asphaltene) of Venezuelan 380 crude oil was studied. The method of column chromatography separation was used two times. Furthermore, the UV-vis spectroscopy was used to characterize the role of metals in different fractions. Results showed that the content of vanadium in crude oil was much higher than nickel. The metals mainly existed in resins (similar to 20%) and asphaltene (similar to 70%). UV-vis spectroscopy had also confirmed the presence of vanadium porphyrins in resins and asphaltene.
