Abstract
Asphaltene precipitation is one of the most important problems of the petroleum industry. Asphaltene collapses during petroleum processing and extraction from the well, blocking the pipes and causing many problems. For this reason, asphaltene should be removed from heavy oils. The main objective of this study was to synthesize new nanocomposite materials to be used in oil industry to prevent asphaltene deposition. The adsorption of asphaltenes from toluene solutions onto NiO/polyHIPE nanocomposite was investigated in detail. Asphaltene adsorption capacities of the polyHIPE-based nanocomposites were determined. Asphaltene adsorption kinetics and isotherms were obtained. It was seen that the pseudo-second-order model provided a good fit for the experimental data while the pseudo-first-order model did not. It is concluded that the synthesized and characterized polymer nanocomposites are important for the oil industry owing to having potential use as an adsorbent.
