Steady‐State and Dynamic Reactor Models for Hydrotreatment of Oil Fractions: A Review

Comparison of kinetic and reactor models to simulate a trickle-bed bench-scale reactor for hydrodesulfurization of VGO

“…where n 1 = 1.8, n 2 = 0.96 and K S H 2 S ¼ 5:1668e 4:092 T and T is in Kelvin. k app was correlated with k in as follows:…”

“…Also reports over the most common approaches to simulate the tricklebed reactor in which HDS is carried out have been summarized [4]. However it has been recognized that even when the vast literature reproduces reasonable well particular HDS process it is difficult to compare among several approaches the best reactor and kinetic model for the same process due to the incomplete experimental data [5].…”

“…Stochastic and deterministic approaches for modeling the hydrotreatment process have been used [4]. Although each one exhibits different advantages and disadvantages it seems that deterministic reactor models can be a good selection because limited data are required and reliable information can be obtained from them.…”

“…Extensive reviews in the literature have appeared regarding hydrodesulfurization of model compounds, petroleum fractions, and heavy oils concerning the most important features associated to that process, that is kinetics and reactor modeling [2][3][4][5]. Also reports over the most common approaches to simulate the tricklebed reactor in which HDS is carried out have been summarized [4].…”

Optimal Design of a Trickle Bed Reactor for Light Fuel Oxidative Desulfurization Based on Experiments and Modeling

“…The tortuosity factor ( ) of the pore network is used in the calculation of because the pores are not oriented along the normal direction from the surface to the center of the catalyst particle 35 , which is:…”
