Heavy oil, commonly defined by high density, viscosity, and heavy components
distinguishing it from light oil, has a peculiar nature with respect to emulsification. In this …

Previously, asphaltene science had been hindered by many significant uncertainties
regarding molecular weight, molecular structure, and nanocolloidal characteristics in …

Asphaltenes and resins remaining after heavy crude oil deasphalting (termed asphaltenes)
require rational utilization. Due to their surface activity, such utilization can consist in …

The present article reviews techniques to address central flow assurance and separation
issues. It is our purpose to update the need for extended information in order to draw …

Asphaltene nanoaggregates from three diverse source materials coal-derived asphaltenes
dominated by aromatic carbon, petroleum asphaltenes with comparable abundances of …

Whole asphaltenes (WA) were fractionated by the E-SARA method according to their
adsorption characteristics at oil–water interfaces from either toluene or heptol solutions …

During the production and transportation of deep-water oil and gas, the low-temperature and
high-pressure operating environment might induce hydrate formation and eventual …

Comparisons of the properties of asphaltenes with very different chemical structures are
essential to unravel their structure–function relationships. The different classes of …

Asphaltene molecular and nanocolloidal structures have largely been resolved enabling
development of structure–function relations of asphaltenes. Atomic force microscopy (AFM) …

Asphaltenes are a solubility class of crude oils comprising polyaromatic and heterocyclic
molecules with different interfacial activities. The previously neglected effects of …
