Different fractions of a heavy crude oil supported in neutral, acid and basic alumina, were isolated by Soxhlet extraction using solvent such as acetonitrile, methanol, n-heptane, toluene and tetrahydrofuran. The natural surfactants (SN) of the neutral fractions were extracted using mixtures of oil...
