Adsorption-desorption of n-c 7 asphaltenes over micro- and nanoparticles of silica and its impact on wettability alteration

Abstract In this work, a study of the adsorption/desorption of n-C7 asphaltenes at low and high concentrations (100 - 30000 mg/L) was performed for which the effects of adsorbent particle size (nano and microsilica), pressure, solvent, and temperature were evaluated. Adsorption/desorption tests on d...
