A kinetic model for the slurry-phase hydrocracking of vacuum residue was proposed under conditions of: 410–450 °C, 0.25–1 hr⁻¹, 160 bar, 1500 Nm³/m³ of H₂ to oil ratio, and 500 ppm catalyst (Mo-octoate). A five-lump model with ten reaction pathways was adopted to describe the hydrocracking kinetics, while the hydrotreating reactions were modeled by the power-law approach. The kinetic parameters were estimated considering the change in liquid density with reaction time. The kinetic model predicted product yields and concentrations with an average error of less than 10%. As for the hydrocracking reaction, it was demonstrated that the secondary cracking of VGO mainly produced MD at high temperature and the high conversion of RES. As for hydrotreating, it was confirmed that asphaltene conversion proceeded to increase the removal level of other impurities. Finally, a hydrogen consumption rate model was proposed based on HCK and HDT, which provides consistent information for further uses in reactor modeling and process modeling.
