The necessity to upgrade the bottom of the barrel into cleaner fuel and more valuable
products is continuously increasing. The most common and essential process in refineries to …

An oil-soluble CoMo 6 heteropolyacid was synthesized by modifying the heteropolyacid with
a surfactant dioctadecyl dimethyl ammonium chloride, and then was used to prepare highly …

Most of the characterization of SARA fractions of heavy crude oils during hydrocracking
reactions is focused only on asphaltenes, and scarce works are devoted to analyze the …

The heavy crude oil of the Mordovo-Karmal deposit was cracked in the presence of NiCr/WC
catalyst. The catalytic upgrading heavy crude oil was carried out in the batch reactor at 450° …

Ebullated bed vacuum residue hydrocracking and fluid catalytic cracking (FCC) are among
the most profitable processes in modern refining. Their optimal performance is vital for …

The structural elucidation of hydrocarbons still remains a challenge for petroleomics
characterization using ultrahigh-resolution mass spectrometry (UHRMS). Double-bond …

A better understanding of the hydrodemetallization kinetics of organometallic constituents is
crucial for the development of catalysts for petroleum residue. Three characteristic fractions …

In order to clarify the effect of blending heavy atmospheric residues (AR) and light AR on
reactivities for hydrodesulfurization (HDS), hydrodenitrogenation (HDN), hydrodevanadium …

The objective of this study is to evaluate the catalyst by introducing atmospheric residue of
heavy crude (H-AR) that secures full comprehensive characteristics and converts into a …
