【 摘 要 】

The influence of fluorine concentrationon the synergism between Co/γ-Al2O3and MoAy-Al2O3 stacked beds separated by 3-mmof γ-Al2O3Fx(x = 0 - 2.5%), in the hydrodesulphurization of refractory molecules containedin gasoil, under operating conditions similar to those of industry, was studied.The results shown, that the synergism increases with F content, reaching a maximumat 0.8% of fluorine, which it is related to changes in zero point of charge(ZPC) and acid strength, due to the incorporation of fluorine. The conversionof most refractory molecule reported is favoured by fluorine.
