The effect of surface area of copper/zirconia adsorbents on the adsorption of thiophene (T) and dibenzothiophene (DBT) was studied. Adsorbents were prepared with different loads of copper (1-6%), using as support zirconias ...

In this work the adsorption of 4,6-dimethyldibenzothiophene (4,6-DMDBT) on different supports (SiO2, Al2O3, zeolite 4A, zeolite 13X, natural zeolite, and activated carbon), incorporating on its surface different first ...

A study is made of Mn//Mo, Fe//Mo, Co//Mo, Ni//Mo, Cu//Mo or Zn//Mo stacked beds systems, separated by g-AI 2O 3, in the gas-oil hydrodesulphurization reaction, under experimental conditions similar to those industry. The ...

The effect of phosphorus content on Mo/γ-Al2O3 sulfide catalysts for the conversion of 2-methoxyphenol (guaiacol) was studied. The catalysts were prepared by successive impregnation of P (0.5, 1.0, 2.0. 3.0 and 5.0 wt.%) ...

The influence of P concentration on the synergism between Co/γ-Al 2O 3 or Ni/γ-Al 2O 3 and Mo/γ-Al 2O 3 stacked beds separated by a 3-mm stack of P x/γ-Al 2O 3 is studied in the hydrodesulphurization of gasoil under operating ...

The synergism effects by hydrogen spillover on M D//Re stacked bed systems and M D (M D = Mn/γ-Al 2O 3, Fe/γ-Al 2O 3, Co/γ-Al 2O 3, Ni/γ-Al 2O 3, Cu/γ-Al 2O 3 or Zn/γ-Al 2O 3) on two real diesel feeds with different sulphur ...
