|Title:||Kinetic And Reactor Models For Hdt Of Middle Distillates|

|Abstract:||Hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) of middle distillates over a commercial Ni-Mo/γ-Al 2O 3) have been studied under wide operating conditions (340 to 380°C and 38 to 98 atm), A Power Law model was presented to each one of those reactions. The parameters of kinetic equations were estimated solving the ordinary differential equations by the 4 th order Runge-Kutta-Gill algorithm and Marquardt method for searching the set of kinetic parameters (kinetic constants as well as the order of the reactions). An adiabatic diesel hydrotreating tricklebed reactor packed with the same catalyst was simulated numerically in order to check up the behavior of this reaction system. One dimensional pseudo-homogeneous model was used in this work. For each feed, the mass and energy balance equations were integrated along the length of the catalytic bed using the 4 th Runge-Kutta-Gill method. The performances oftwo industrial reactors were checked. © 1999 Elsevier Science Ltd.|
