Abstract
This work is part of a general effort to reduce the sulfur content of fuels to satisfy new European regulations. The objective was to determine the influence of several activating agents during sulfidation on the activity of hydro-desulfurization (HDS) catalysts. Indeed, sulfidation is a critical step to achieve a good level of HDS activity on sulfide catalysts. Under industrial conditions, the activation by organo-sulfide compounds would be more beneficial to obtain active catalysts than the use of hydrogen sulfide. A systematic study of the various operational parameters of the activation process was thus carried out by comparing precisely activation by H{sub 2}S or by organo-sulfides. This study reveals that the recognized advantage of organo-sulfides compounds has not a 'purely chemical origin' but would be more probably related to a heating and/or thermodynamic effect which depends on the processes and on the implementation of sulfidation under the industrial conditions.
