252 literature sources and about 5000 crude oil assays were reviewed in this work. The
review has shown that the petroleum characterization can be classified in three categories …

Slurry-phase hydrocracking is an effective technology for the conversion of heavy oils to
clean and light fuels. Herein, trialkylmethylammonium molybdate ionic liquids (ILs) with …

The intercriteria analysis developed on the base of intuitionistic fuzziness and index
matrices was applied to evaluate processing data of the LUKOIL Neftohim Burgas H-Oil …

Abstract 165 crude oils with viscosity, density, and molecular weight variation in the range
0.54–24135cP; 0.746–1.016 g/cm 3; 117–579 g/mol respectively were examined for …

In this research, six various asphaltenes extracted from crude oil mixtures of three Russian
refinery plants and some heavy residues of these plants were studied with applying …

Reaction constants for vacuum gas oil (VGO) hydrocracking and slurry phase
hydroconversion of residues are calculated and positioned with respect to results from the …

Slurry-phase hydrocracking for heavy oil upgrading is a challenging technology in the
petroleum refining industry. We prepared various P-containing Mo precursors to elucidate …

The Urals and Siberian vacuum residues are considered difficult to process in the ebullated
bed hydrocracking because of their increased tendency to form sediments. Their achievable …

Vacuum residues (VR) are the bottom of the barrel products left after vacuum distillation of
crude oils. VR are primarily used as feedstock for production of syn-gas and hydrogen via …

The high-viscosity residual fractions obtained during the secondary processing of crude oil
are widely used as components in the production of marine fuels. Because of the high …
