An original method to study the local environment of vanadyl-containing components of
heavy oils based on fine-tuning simulation of their electron spin resonance (ESR) spectra in …

To gain a profound understanding of the reaction pathway and the controlling step of
residue oil slurry-phase hydrocracking over Fe 2 O 3 catalyst, a six-lumped kinetic model …

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

It has been shown for the first time that the high-temperature treatment of heavy oil with a
high content of asphaltenes at 350–450° C without a catalyst or H2 leads to the formation of …

The electron paramagnetic resonance (EPR) technique was used to study the behavior of
the asphaltenes from the Merey crude oil (ASCM), its vacuum residue (ARVM), its fractions …

The spectrophotometric studies of vanadylporphyrin complexes isolated from the oil of the
Severnoe Buzachi field with absorption maxima at 534 and 573 nm showed that the …
