Understanding mechanisms of asphaltene adsorption from organic solvent on mica.
The adsorption process of asphaltene onto molecularly smooth mica surfaces from toluene solutions of various concentrations (0.01-1 wt %) was studied using a surface forces apparatus (SFA). Adsorption of asphaltenes onto mica was found to be highly dependent on adsorption time and asphaltene concentration of the solution. The adsorption of asphaltenes led to an attractive bridging force between...
متن کاملAssessing the Asphaltene Adsorption on Metal Oxide Nanoparticles
The Taguchi design of experiments (DOE) approach is adopted here to evaluate the impact ofeffective factors such as nanoparticles type, nanoparticles to model solution mass ratio, asphaltenestructure, and temperature on asphaltene adsorption equilibrium. Herein, the toluene-asphaltenesolution model is applied. Three commercially nanoparticles (SiO2, Al2O3, and TiO2) are used.<...
متن کاملAdsorption of Wine Constituents on Functionalized Surfaces.
The adsorption of macromolecules on solid surfaces is of great importance in the field of nanotechnology, biomaterials, biotechnological, and food processes. In the field of oenology adsorption of wine macromolecules such as polyphenols, polysaccharides, and proteins is much less desirable on membrane materials because of fouling and reduced filtering performance. On the other hand, adsorption ...
متن کاملFunctionalized mesoporous solids based on magadiite and [Al]-magadiite.
Novel hybrid mesoporous and functionalized materials with controllable surface area and pore dimensions with functional basic sites (-NH2) were synthesized from magadiite and [Al]-magadiite as layered silicate precursors. The variable pore structure and properties of these materials were investigated in these solids by using different CTA(+)/Na(+) (CTA(+) = cetyltrimethylammonium cation) molar ...
متن کاملEffect of surface acidity and basicity of aluminas on asphaltene adsorption and oxidation.
This study investigates the effect of surface acidity and basicity of aluminas on asphaltene adsorption followed by air oxidation. Equilibrium batch adsorption experiments were conducted at 25°C with solutions of asphaltenes in toluene at concentrations ranging from 100 to 3000 g/L using three conventional alumina adsorbents with different surface acidity. Data were found to better fit to the F...
