Estudo do desempenho de reator de leito gotejante aplicado ao processo de hidrodessulfurização do petróleo

A heterogeneous reactor model in one-dimensional transient was developed to simulate a trickle bed reactor (TBR) applied to hydrodesulfurization (HDS) of oil. The model incorporates the resistance to mass transfer in gas-liquid and liquid-solid interfaces and an expression of the reaction rate based kinetic model of Langmuir-Hinshelwood type. Through parameter estimation, the model was fitted based on experimental data from a pilot-scale reactor and then validated under different experimental conditions. Finally, it were studied both H 2 S inhibiting effect and the effect of operating conditions on the HDS conversion, such as pressure, temperature, and liquid hourly space velocity (LHSV).
