Kinetic and thermodynamic equilibrium of asphaltenes sorption onto formation rock: evaluation of the wash in the adsorptive properties

The main objective was to obtain kinetic and thermodynamic equilibrium of asphaltene sorption onto powder ROCK obtained from the Guadalupe formation (washed and unwashed) at different times, temperatures and concentrations. However, the effect of temperature in the equilibrium sorption is not signif...
