Special Issue Information

Dear Colleagues,

The subsequent depletion of the world’s conventional hydrocarbon resources makes the development of heavy oil reservoirs relevant. Moreover, heavy oil resources can be contrasted with conventional hydrocarbon resources. The main problem in the production and transportation of heavy oil is its abnormally high viscosity that is dependent on significant content of resins and asphaltenes. Thermal production methods are applied to recover heavy oil. Heat energy reduces the viscosity of oil in reservoir rocks and particularly transforms the heavy components as a result of aquathermolysis or in-situ oxidation reactions. However, it is possible to increase the efficiency of thermal production methods and consequently the transportation of heavy oil via the introduction of various catalytic systems. This could be oil-soluble transition metal-based compounds that decompose directly in-situ with further formation of the active form of catalysts in reservoir conditions, or stabilized nanoparticle suspensions or emulsions of nanoparticle precursors, etc. The analogical approaches can be applied in downstream processes of heavy oil in order to significantly facilitate the composition of crude oils and transform resins and asphaltenes by using hydrogen. In this case, it is possible to use dispersed slurry systems as well as supported catalysts on specially selected carriers. Among the problems of synthesizing catalysts for heavy oil upgrading, a special focus is given to their formation, structure, and stability in response to conversions.

Understanding the conversion behaviors of heavy oil in various environments as well as reservoir conditions, and the conversion direction of specific compounds and their groups from oil composition such as resin and asphaltene components, is necessary for the design of modern production, transportation, and refinery technologies of heavy oils.

This paper discusses the role of magnetite in the conversion of heavy oil from the Ashal’cha reservoir. The effect of catalysts on the in-situ upgrading of heavy oil is directed on the reduction of high-molecular components of oil such as resins and asphaltenes and their molecular masses. Moreover, it is directed on the significant increase in saturates and aromatic fractions. Measuring the temperature-dependent viscosity characteristics revealed the tremendous viscosity decrease of the obtained catalytic aquathermolysis products. X-ray analysis exposed the composition of the initial catalyst that consisted of mixed iron oxides (II, III), as well as catalysts that were extracted from the treated crude oil. The particle size of the catalysts was investigated by scanning electron microscopy. According to the SEM data, aggregates of 200 nm were formed that were in the range of ultra-dispersed particles (200 to 500 nm). Full article

A new approach for characterization of fluid catalytic cracking (FCC) catalysts is proposed. This approach is based on computational visual analyses of images originating from field emission scanning electron microscopy (FE-SEM) studies coupled with elemental mapping via electron dispersive x-ray spectroscopy (EDX) analyses. The concept of contaminant metal mobility is defined and systematically studied through quantification of interparticle transfer and intraparticle penetration of the most common FCC contaminant metals (nickel, vanadium, iron, and calcium). This novel methodology was employed for practical quantification of intraparticle mobility via the Peripheral Deposition Index (PDI). For analyzing and quantifying interparticle mobility, a new index was developed and coined “Interparticle Mobility Index” or IMI. With the development and practical application of these two indices, this study offers the first standardized methodology for quantification of metals mobility in FCC. This novel systematic approach for analyzing metals mobility allows for improved troubleshooting of refinery-specific case studies and for more effective research and development in contaminant metals passivation in FCC catalysts.

This study represents the results of ex-situ synthesis and research of the properties of concentrated suspensions with new catalysts for petroleum residue hydro-conversion. Suspensions were prepared and stabilized in a petroleum residue medium through reverse emulsions containing water-soluble Mo-precursor and S-containing agents (elemental sulfur, thiocarbamide) in the absence of a solid carrier. The resulting ex-situ catalyst dispersions had Mo content of 6–10 wt % and contained nanosized and submicron catalyst particles stabilized in a petroleum residue medium. The effects of S-containing agents on the properties of catalytic particles (sulfidation level, dispersity, structural and morphological features) were studied. The synthesis conditions for the optimal ex-situ catalyst providing the lowest coke yield (0.2 wt %) and the highest conversion (55.5 wt %) during petroleum residue hydro-conversion in a single pass mode have been determined.
