Petroleum asphaltenes, a by-product of crude oil extraction, are a promising feedstock for
the development of high-value carbonaceous materials because of their high carbon content …

Adsorption of asphaltene onto mineral or metal surface is an undesirable process with
several adverse effects such as wettability alteration, fouling pipelines/equipment …

The aggregation behaviors of asphalt on the hydrate surface with different surfactant
coverages were studied by molecular simulations. The molecular polarity index of asphalt …

Molecular dynamics was employed to investigate the micro-mechanism of water and asphalt
on hydrate aggregation, addressing the mechanism of aggregation caused by hydrates …

Currently, the alteration of external factors during crude oil extraction easily disrupts the
thermodynamic equilibrium of asphaltene, resulting in the continuous flocculation and …

Asphaltene stability can be perturbed during the oil production and transportation, leading to
asphaltene precipitation and deposition. Chemical inhibitors are usually added to the oil …

Asphaltene precipitation is one of crucial problems in oil industry that negatively affects oil
