     this paper describes a dynamic heterogeneous one-dimensional model of trickle-bed reactor used for catalytic hydrotreating of oil fractions. the model takes into consideration the main reactions occurring in the hydrotreating process: hydrodesulfurization, hydrodenitrogenation, hydrodearomatization (mono-, di-, and polyaroamatics), olefins hydrogenation, and mild hydrocracking (gas oil, naphtha, and gases). kinetic parameters were determined from experimental data obtained in an isothermal bench-scale reactor during hydrotreating of atmospheric gas oil coming from a heavy crude oil over a commercial como catalyst. the developed model was used to predict the dynamic behavior of an industrial hydrotreating reactor within a wide range of reaction conditions. changes in concentration, partial pressure, and temperature profiles are simulated and discussed as a function of reactor axial position and time. the simulation results obtained with the proposed dynamic model showed good agreement with experimental data.
