Abstract
The preparation of an active hydrodesulphurization catalyst involves the impregnation of the oxidic support with molybdenum and cobalt compounds, followed by drying and calcination to obtain well-dispersed oxides of these elements [1,2]. The preparation finishes with the conversion of the oxides into the catalytically active phase by sulphidation. Being an essential part of the preparation, it is important to know the mechanism of the sulphidation process and to identify the elementary reaction steps that constitute the conversion from oxides to sulphides, in dependence of how the HDS catalyst is prepared. The sulphidation of molybdenum and cobalt-promoted molybdenum catalysts forms the main subject of this paper.
