Recently, significant changes in petroleum sources have been observed where light crude
sources are becoming heavy or extra heavy, containing a large number of contaminants (S …

Asphaltenes, and their related issues, have been the focus of many literature investigations.
However, in-depth analysis of asphaltenes structure and its relation to asphaltenes stability …

In crude oil production and processing, asphaltene aggregation followed by precipitation is
a major problem for the oil industry as it causes deactivation of catalysts, blocking pipelines …

Hydrothermal treatment is a green and sustainable technology to upgrade heavy oil with
water acting both as a solvent and a reactant. However, water reactivity under subcritical …

This research aims to the microwave-assisted catalytic cracking of the asphaltene by using
nanoparticles of SiO 2, Al 2 O 3, clay, and ZnO acting as a nanocatalyst. The nanoparticle …

The adsorption of asphaltenes onto nanoparticles (NPs) has received a lot of attention in
recent years. However, the effect of the measurement technique on the adsorption isotherms …

Hydrogen donation is the key to supercritical water upgrading of heavy oil, because it
benefits light distillate production and inhibits condensation, but the mechanism is still …

The main objective of this work is to determine the effect of thermal cracking on asphaltene
molecular structure by using nuclear magnetic resonance (NMR). The NMR is used to …

The main purpose of this study is to elucidate the effect of catalyst on asphaltene molecular
structure during hydrocracking of C 5-isolated asphaltene. Remained asphaltene and coke …

Few-layer carbon materials were synthesized from asphaltene by a top-down approach
using a thermal treatment. Asphaltene was carbonized in a rotating quartz-tube furnace …
