Abstract: 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.

Abstract: Provided is a zeolite-based adsorbent in the form of agglomerates, where the adsorbent having a tortuosity factor, calculated from the pore distribution determined by mercury intrusion porosimetry, of greater than 1 and less than 3. The adsorbent also has a porosity as determined by mercury intrusion porosimetry of between 25% and 35%. The adsorbent is useful in the field of separations in particular in a process for separating para-xylene from aromatic hydrocarbon isomer fractions containing 8 carbon atoms.
