International audience; The aggregation and adsorption of asphaltenes is of great interest due to their negative effects on the oil industry. Asphaltenes form aggregates, even at low concentrations, producing groups of molecules with different molecu

The comprehension of dominant driving forces for Asphaltene self aggregation and adsorption onto surfaces are still under discussion. Experimental results point to combined effects of the local electrical fields, molecular polarization, and dispersio

Metal compounds such as vanadyl and nickel porphyrins present in crude oils are associated to the most polar fraction defined as asphaltenes. The amount and kind of these compounds in the crude oil depend of the variations in origin, maturity, pressu
