Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

With the ever increasing demand for energy to meet the needs of growth in population and
improvement in the living standards in particular in developing countries, the abundant …

Asphaltene adsorption at solid surfaces is a ubiquitous phenomenon that begins within the
production well and continues through the entire production chain. It is generally an …

This study investigates the adsorption and oxidation of asphaltenes onto nanoparticles. Six
different metal oxide nanoparticles were employed, namely, Fe3O4, Co3O4, TiO2, MgO …

Asphaltene adsorption onto nanoparticles is an attractive subject for the heavy oil industry
for two important reasons. First, nanoparticles would remove asphaltenes from the heavy oil …

Understanding the acid− base behavior of silica surfaces is critical for many nanoscience
and bionano interface applications. Silanol groups (SiOH) on silica surfaces exhibit two …

The few existing surface complexation models (SCM) for the brine-oil interface have
important limitations: the chemistry of each crude oil is not considered, they cannot capture …

Despite the broad range of interest and applications, controls on the surface charge of crude
oil in aqueous solution remain poorly understood. The primary data source to understand …

The adsorption of asphaltene on different clay minerals (kaolinite, illite, montmorillonite) and
mineral oil reservoir rocks was studied. In toluene solution, specific adsorption was …

Nanoparticles (NPs) have been recently recognized as effective asphaltenes adsorbents
and deposition deterrents. The objective of this work is to provide a critical review and …
