Asphaltenes, as the heaviest and most polar fraction of petroleum, have been characterized
by various analytical techniques. A variety of fractionation methods have been carried out to …

Advances in high-resolution Fourier transform ion cyclotron resonance mass spectrometry
(FT-ICR MS) enable molecular-level characterization of ultracomplex asphaltene samples …

Asphaltenes are considered to be the heaviest and most polar fractions of crude oils and are
frequently implicated in problems encountered during production and refining as a result of …

The molecular weight of asphaltenes has been a controversy for several decades. In recent
years, several techniques have converged on the size of the fused ring system; indicating …

Heavy oil and bitumen drive the leading energy supply in Canada. Several techniques,
including in situ thermal methods and mining, have been applied to the recovery of these …

The goal of predictive science is to establish structure− function relations for a system of
interest. The obvious first step is to determine the structure of the system. Predictions in …

The proposition of the hypothesis-relating structure with properties of asphaltenes is a very
important endeavor. In view of their complexity, being an intricate mixture of high-molecular …

User's Handbook; CRC Press: Boca Raton, FL, 1999) to calculate components of solubility …

This study aims to analyze the aggregation state of A1 and A2 asphaltene subfractions and
their influence on the adsorption and reactivity of ceria-based nanoparticles. To this aim, a …

The production and transportation of highly viscous heavy and extra-heavy crude oils are
two of the paramount concerns in the oil and gas industry due to logistical difficulties and …
