Few-layered MoSe2 nanosheets are significant for energy storage due to more active edges and improved conductivity. Herein, the cavity confinement effect of structure-defected UiO-66-NH2 is applied to host H3PMo12O40 units, which can be transformed…
Oxidation of petroleum asphaltenes by potassium iodide (KI) is described. Oxidation under mild conditions is shown to be accompanied by iodination of the asphaltene aromatic core. The inducing reaction is the oxidation of sulfide sulfur atoms in the…
A better understanding of the nature of crude oil compounds that preferentially interact with certain types of solids is essential to visualize solutions to challenges in oil fields, such as enhancing the oil recovery factor, via wettability…
This article presents the results from the primary treatment of heavy crude oil in the presence of activated carbon and a supercritical aqueous fluid. This makes it possible to reduce the content of sulfur and resinous-asphaltene substances…
A thermal processing of waste tires in the presence of a natural zeolite catalyst from the "Tayzhuzgen" field (Eastern Kazakhstan) is detailed. The hydrogen sources utilized were heavy residues from oil refinement. The elemental and phase composition…
Despite the numerous works devoted to using of different types of nanoparticles for treatment of asphaltene related issues, the potential applications of carbon nanostructures for controlling of asphaltene precipitation have not been addressed in the…
