“…Important works have been carried out in the last period to upgrade heavy cuts, like atmospheric or vacuum residues, into valuable distillates using catalysts (Shimada et al, 2009;Elizalde et al, 2009;Rana et al, 2007;Ancheyta et al, 2005;Zhang et al, 2005;Kressmann et al, 1998;Morel et al, 1997;Toulhoat et al, 1990). This conversion requires demetallation (Ni and V), sulfur and nitrogen subtraction.…”

“…Kressman et al [1] found that asphaltenes content, asphalteneto-resin ratio and metals content in the feed, play an important role in the catalyst performance. They reported that a large decrease of hydrodesulfurization (HDS) and hydrodemetallization (HDM) reaction rates occur when the asphaltenes content of the feed increases.…”

In order to be able to upgrade the heaviest part of the crude oil one needs to remove several impurities, such as sulfur or metals. Residue hydrotreatment in fixed beds, under high hydrogen pressure can achieve high removal performances, with an industrial catalysts optimized staging. Despite the recent improvements, petroleum residues remain very difficult to describe and characterize in detail. Several kinetic models have been developed, but mostly they are feed dependant and their predictions are not satisfying for residues of different origins. Based on a recent study comparing residue properties and the differentiating physical-chemical properties responsible for reactivity [1], the present work develops a 2 hydrotreatment kinetic model coupled with mass transfer in the catalyst which attempts to simulate the different residue performances. After estimation of kinetic parameters for a given residue, the model was validated for three other residues. This new model is able to take into account differences in residue characteristics and gives fairly good simulations of residues performances.
