Changes of Asphaltenes' Structural Phase Characteristics in the Process of Conversion of Heavy Oil in the Hydrothermal Catalytic System-Ural Basin, Republic of Tatarstan) and the peculiarities of the changes of its asphaltenes' structural phase

Concentration of paramagnetic centres at low-temperature thermal destruction of asphaltenes of heavy petroleum distillatesConcentration of paramagnetic centres at low-temperature thermal destruction of asphaltenes

The relationship between bitumen microstructure and viscous flow that the main factor determining the structure of the surface is not only the content of asphaltenes

Effect of catalytic aquathermolysis on high-molecular-weight components of heavy oil in the ashal'cha field and composition of the resins and asphaltenes in aquathermolysis was studied by PMR and IR spectroscopy.

Influence of Oil Composition on its Resistance to Asphaltene Precipitation chromatography, and IR spectrometry, which allow to determine the content of resins, asphaltenes, and saturated

Composites Based on Polyurethane and Modified Petroleum AsphaltenesIn this work, polyurethane composites with petroleum asphaltenes and their modified derivatives

Electron paramagnetic resonance study of rotational mobility of vanadyl porphyrin complexes in crude oil asphaltenes: Probing the effect of thermal treatment of heavy oils©2014 American Chemical Society. The structural properties of crude oils and asphaltenes

Fractionation of asphaltenes for determination of their composition and structure in case of heavy oil from Ashal'cha field© Published under licence by IOP Publishing Ltd. The asphaltene fractions from initial crude oil

Characteristics of compatability of high-viscosity oils is determined. It is shown that the change in asphaltene content in the blends is non-additive.

Molecular Dynamics and Proton Hyperpolarization via Synthetic and Crude Oil Porphyrin Complexes in Solid and Solution StatesThe use of vanadyl porphyrins either in synthetic compounds or naturally occurring in asphaltenes
