摘要： A selective hydrogenation catalyst contains an active phase having a group VIB metal and a group VIII metal, and a porous support containing alumina. The group VIB metal content is between 1 and 18% by weight relative to total weight of the catalyst, and the group VIII metal content of the active phase, measured in oxide form, is between 1 and 20% by weight relative to total weight of the catalyst. The molar ratio between the group VIII metal and the group VIB metal is between 1.0 and 3.0 mol/mol. The group VIII metal is homogeneously distributed in the porous support with a distribution coefficient R of between 0.8 and 1.2, measured using a Castaing microprobe, and the group VIB metal is distributed at the periphery of the porous support with a distribution coefficient R of less than 0.8.

摘要： The invention describes a mass for scavenging mercaptans which is particularly suitable for the treatment of olefinic gasoline cuts containing sulfur such as gasolines resulting from catalytic cracking. The scavenging mass comprises an active phase based on group VIII, IB or IIB metal particles which is prepared by a step of bringing a porous support into contact with a metal salt of said group VIII, IB or IIB metal and a step heating the resulting mixture to a temperature above the melting point of said metal salt. The invention also relates to a process for using said scavenging mass for the adsorption of mercaptans.
