The FCC gasoline represents 30 to 50% of the total commercialized motor fuel but contributes up to 90% of the sulfur present in the pool and consequently has to be desulfurised. However its olefin content is around 30 to 40wt% and the hydrogenation reactions must be limited in order to preserve a high octane number [2]. A selective hydrotreating catalyst is thus required : high hydrodesulfurization (HDS) activity with the lowest olefin hydrogenation (HYDO). 收起
