The reactor model is based on an axial dis- Simulation persion. The hydrocracking kinetic model takes into account a ﬁve-lump model previously reported in the lit- Slurry-phase reactor erature. The hydrotreating reactions simulated are: hydrodesulfurization (described by Langmuir–Hinshelwood Heavy oil kinetics), hydrodenitrogenation (for basic and non-basic nitrogen), hydrodeasphaltenization and hydro Hydrocrackig Conradson carbon removal (modeled with power-law approach). All the intrinsic kinetic parameters and cor- Hydrotreating relations were taken from the literature. The performance for the slurry-phase reactor was compared with a continuous stirred tank reactor. Dynamic simulations and steady-state predictions agreed with the expected behavior of the
