Abstract
A description follows of a bimetallic catalyst, obtained by dispersing in sequence and alternating the precursors of the single metal components of the catalyst on a carrier, and a process for the synthesis of hydrogen peroxide by the direct reaction of hydrogen with oxygen, in a solvent medium containing a halogenated promoter and an acid promoter, in the presence of said catalyst.

A process for the synthesis of hydrogen peroxide by means of the direct reaction of hydrogen with oxygen, in a solvent medium containing a halogenated promoter and an acid promoter, in the presence of a bimetallic catalyst obtained by dispersing in sequence and alternating the single metal components of the catalyst on a carrier.
A bimetallic catalyst useful for the production of hydrogen peroxide obtained by dispersing in sequence and alternating the precursors of the single metal components of the catalyst by :
- (a) preparation of the solutions or suspensions of the precursors of the single metal components of the catalytic system;
- (b) dispersion of the solutions or suspensions obtained in (a) in sequence on a carrier;
- (c) treatment of the catalyst with a reducing agent of the metal and drying at 120-140° C. between one dispersion and another.
