Catalytic oxidation of heavy residual oil by pulsed nuclear magnetic resonance

Vakhin A.V.; Cherkasova E.I.; Safiulina A.G.; Islamova G.G.; Petrov S.M.; Bashkirtseva N.Y. (2021)

A study on the catalytic oxidation of heavy residual oil (HRO) was carried out. The thermodynamic parameters of components of HRO oxidation products were studied by pulsed nuclear magnetic resonance (NMR). A method for the ...
Conversion of organic matter of carbonate deposits in the hydrothermal fluid

Petrov S.M.; Lakhova A.I.; Safiulina A.G.; Ignashev N.E.; Khelkhal M.A.; Vakhin A.V. (2021)

This present paper investigates the conversion of organic matter in carbonate rocks of the Semiluksko-Mendymsky horizon Volga-Ural Basin under hydrothermal conditions with excess water in subcritical conditions at 613–653 ...
Influence of metal oxides and their precursors on the composition of final products of aquathermolysis of raw ashalchin oil

Petrov S.M.; Safiulina A.G.; Bashkirtseva N.Y.; Lakhova A.I.; Islamova G.G. (2021)

Experiments were conducted simulating hydrothermal conversion of heavy oil in the presence of carbonate, kaolin, Al2 O3, Ni2+ and Cu2+, NiO mixed with poly-α-olefins, C6 H8 O7, C2 H4 O2 at 290–375◦ C and 10–135 bar. Al2 ...
Reactivity of metastable water in hydrothermal heavy crude oil and carbonaceous compounds conversions

Zakieva R.R.; Vasilev E.R.; Karalin E.A.; Petrov S.M.; Bashkirceva N.Y. (2020)

© 2020. The geological reserves of ultra viscous hydrocarbons are enormous and commensurate with the world reserves of conditioned oils. The technologies currently known provide the extraction of only 10 %-15 % of the ...
Study of heavy crude oil composition after a hydrothermal treatment in presence of nanoparticles

Valieva A.A.; Petrov S.M.; Lakhova A.I.; Bashkirtseva N.Y. (2020)

© 2020. The communication presents the results of a study on the hydrothermal conversion of heavy super-viscous crude oil in presence of Al2O3, Fe2O3, NiCO3, and ZnO nanoparticles at temperatures in the range of 350°S-375°S ...
Study of the impact of nonionic additives on the composition and structure of petroleum dispersed systems by IR spectroscopy

Lakhova A.I.; Safiulina A.G.; Islamova G.G.; Amansaryev A.B.; Salakhov I.I.; Petrov S.M.; Bashkirtseva N.Y. (2021)

The article describes a technique for obtaining a quantitative assessment of the composition and structure of the petroleum dispersed system (PDS) and its individual structural formations based on the data of the component ...
Upgrading Heavy Petroleum in Superheated Steam in the Presence of Modified Aluminosilicates

Zakieva R.R.; Bashkirtseva N.Y.; Petrov S.M.; Lakhova A.I. (2021)

Results are presented for a study of upgrading of heavy crude oil with density 0.9857 g/cm3 and sulfur content 3.6 mass % in superheated steam at 355-375°C and pressure up to 14 MPa in the presence of iron-modified natural ...
