“…The FCC conversion was found to depend on only two variables for the studied cases, and these were the content of H-Oil VGO in the FCC feed and the content of FCC SLO in the H-Oil feed. The dependence of FCC conversion on content of H-Oil VGO in the FCC feed and content of FCC SLO in the H-Oil feed is shown in Equation (14).…”

Ebullated bed vacuum residue hydrocracking and fluid catalytic cracking (FCC) are among the most profitable processes in modern refining. Their optimal performance is vital for petroleum refining profitability. That is why a better understanding of their combined action and the interrelations between these two heavy oil conversion processes in a real-world refinery could provide valuable information for further performance optimization. Nine distinct petroleum crudes belonging to the extra light, light, and medium petroleum crude types were processed in the LUKOIL Neftohim Burgas refinery to study the combined performance of two processes: FCC of vacuum gas oil and ebullated bed vacuum residue H-Oil hydrocracking. The operating conditions along with the characterization data of the feeds and products of both processes were evaluated through the employment of intercriteria analysis to define the variables with statistically significant relationships. Maple 2023 Academic Edition mathematics software was used to develop models to predict the vacuum residue conversion level under different operating conditions. The plug flow reactor model with an activation energy of 215 kJ/mol and a reaction order of 1.59 was found to provide the highest accuracy of vacuum residue conversion, with an average absolute deviation of 2.2%. H-Oil yields were found to correlate with the vacuum residue conversion level and the content of FCC slurry oil (SLO), the recycling of partially blended fuel oil, a material boiling point below 360 °C, and the vacuum gas oil (VGO) in the H-Oil feed. FCC conversion was found to depend on the H-Oil VGO content in the FCC feed and the content of FCC SLO in the H-Oil feed.

“…An intriguing aspect of steam injection is its capacity to induce in situ upgrading reactions, such as hydrogenation and aquathermolysis, when combined with appropriate chemical additives like solvents and catalysts. − These interactions within the reservoir depend on various factors, including the additives’ and catalysts’ physicochemical properties, concentration, and residence time. Notably, catalysts significantly impact the decarbonization and desulfurization processes, facilitating environmentally cleaner and more efficient heavy oil upgrading. − …”

This study presents a groundbreaking approach to heavy oil upgrading using water-soluble nickel acetate as a precatalyst, marking a shift from traditional oil-soluble catalysts. We demonstrate that nickel and copper acetates significantly enhance aquathermolysis, reducing the viscosity of heavy oil by almost 58% and the high-molecular-weight fractions from 38.3 to 23.5 wt % while increasing the lighter fractions from 61.7 to 76.5 wt %. The catalytic action of nickel and copper acetates facilitates the structural and compositional transformation of heavy oil, evidenced by the increased H/C atomic ratio and 30% reduction in the initial boiling point. Further, these catalysts yield an increase in light distillate production and promote the formation of stable free radicals, indicating a higher degree of hydrocarbon decomposition. Analytical techniques, including thermogravimetric analysis, kinetic analysis, X-ray diffraction, and scanning electron microscopy, confirm the effective decomposition of nickel and copper acetates into active nickel and copper species, predominantly nanoparticles smaller than 58 nm. The study underlines the potential of water-soluble catalysts such as nickel and copper acetates to enhance steam-based oil recovery and upgrading processes, offering a cost-effective and environmentally friendlier alternative to conventional methods. The ongoing research promises to solidify the role of catalysts in sustainable energy production.
