Abstract

The influence of P concentration on the synergism between Co/γ-Al₂O₃ or Ni/γ-Al₂O₃ and Mo/γ-Al₂O₃ stacked beds separated by a 3-mm stack of P_x/γ-Al₂O₃ is studied in the hydrodesulphurization of gasoil under operating conditions similar to those of industry. The results shown increased Co//Mo and Ni//Mo synergism related to changes in zero point of charge (ZPC), acid strength, and band intensities of diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy due to the incorporation of P into the γ-Al₂O₃ used as separator.
