Distribution of Ni and V in A1 and A2 Asphaltene Fractions in Stable and Unstable Venezuelan Crude Oils
Asphaltenes are a complex mixture of compounds grouped as the colloidal phase in crude oils. Two fractions, A1 and A2, have been isolated from them. A1 is defined as the mayor and practically insoluble fraction, while A2 has a similar solubility to the original asphaltenes in toluene. The studies on...
