摘要

The dynamic modeling and simulation of a continuous slurry phase reactor for catalytic hydrocracking and hydrotreating of an atmospheric residue (312 degrees C+) are reported. The reactor model is based on an axial dispersion. The hydrocracking kinetic model takes into account a five-lump model previously reported in the literature. The hydrotreating reactions simulated are: hydrodesulfurization (described by Langmuir-Hinshelwood kinetics), hydrodenitrogenation (for basic and non-basic nitrogen), hydrodeasphaltenization and hydro Conradson carbon removal (modeled with power-law approach). All the intrinsic kinetic parameters and correlations 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 heavy fractions and impurities hydroprocesing.
