| Abstract | A series of catalysts was prepared using different procedures to incorporate sodium and fluoride into the Co-Mo/Al 2o3 system. A bench-scale high pressure continuous-flow system was used for reactivity
tests. The experimental results have shown that sodium is an inhibitor and fluoride is a promoter for the hydrodesulphurization of bitumen derived from the Athabasca Oil Sands. The fluoride ion was considered to enhance the catalyst Bronsted acidity
and therefore cracking of carbon-carbon bonds. This could improve the access to the catalyst of sterically hindered sulphur atoms in the bitumen. The slower rate of catalyst deactivation when molybdenum and cobalt were added to the catalyst before
the first calcining step was attributed to the greater interaction of the molybdenum with the alumina. This would decrease the number of bare alumina sites which may be prime candidates for coke formation. It would also decrease sintering tendencies
in Mos 2 crystallites. |
