Introduces the reader to the production of the products in a refinery• Introduces the reader to
the types of test methods applied to petroleum products, including the need for …

Asphaltenes, the heaviest and most polar components of crudes, are generally associated
with considerable operational issues in refineries. In order to understand potential …

Hindered diffusion and adsorption phenomena of asphaltene molecules inside the porous
network of hydrotreatement catalysts are discussed in this paper. The kinetics of the global …

This study is focused on evaluating the aggregation behavior of four asphaltene molecules
(PA3-type) dissolved in three different solvents. Hence, solution models composed of …

The objective of this work was to investigate the effect of precipitating environment on
asphaltene precipitation such as, precipitant (n-alkanes: C5, C7, C9, C12, C14), asphaltene …

Solvent deasphalting of the bottom of vacuum distillation columns (vacuum residue, VR) is a
process practiced worldwide. In Northern Alberta, a solvent deasphalting plant was …

The results of experimental studies of carbon materials, which are formed in the plasma of a
direct current (DC) arc discharge initiated in open air from the asphaltenes of different …

This study presents analysis of asphaltenes isolated from two crude oils: naphthenic-
aromatic biodegraded oil and paraffin-naphthenic oil, which have been used as precursors …

In this paper, the nanoclay particles were introduced as mobile adsorbents in oil reservoirs
to adsorb the asphaltenes, reduce the viscosity and enhance the dispersion. The objective …

The aim of this work is to investigate the influence of the catalyst and the operating
temperature on the sediments formation occurring during vacuum residue hydroconversion …
