The Influence of Hydrodearomatisation Reaction Kinetics on the Modelling of Sulphur and Aromatics Removal from Diesel Fuel in an Industrial Hydrotreating Process

Over the years, hydrotreating process has been considerably improved in order to facilitate production of environmentally friendly diesel fuels by reducing sulphur and aromatics concentrations, as mandated contemporary emissions regulations. In this study, different kinetic models for hydrodearomatisation reaction influence rate on performance industrial trickle bed reactor gas oil light cycle fractions were analysed. The impact temperature, catalyst wetting efficiency, conversion determined. results simulations compared with experimental data from an test run best model observed is proposed. Reactor overall efficiency strongly dependent kinetics hydrodearomatisaton respect but even more so temperature increase reactor, which affects all key catalytic parameters, thus conversion. Based obtained simulation results, it could be concluded that reaction. predictions outlet well aromatic (deviation value 0.87 K, 0.01% 2.57%, respectively) are achieved Langmuir–Hinshelwood proposed Owusu-Boakye.
