A catalytic system for the production of synthesis gas by reacting light hydrocarbons, preferably methane, with CO2 is described formed from: one or more compounds of metals of the platinum group, preferably chosen from rhodium, ruthenium and iridium; a support consisting of inorganic compounds chosen from oxides and/or spinels of aluminium, magnesium, zirconium, silicon, cerium and/or lanthanum, possibly in the presence of alkali metals, in which the weight percentage of the metal or metals of the platinum group in the catalytic system is between 0.01 and 20%, and preferably between 0.1 and 5%.

A catalytic system for the production of synthesis gas by reforming light hydrocarbons with CO2, characterized by being formed from: one or more compounds of metals of the platinum group; a support consisting of silicated aluminum, magnesium, cerium or lanthanum oxides; in which the weight percentage of the metal or metals of the platinum group in the catalytic system is between 0.01 and 20%, said support being prepared by a process consisting essentially of the condensation of an aluminum, magnesium, cerium or lanthanum oxide with a silicon compound containing hydrolyzable organic groups, and the subsequent removal of the non-hydrolyzed organic residues by combustion in the presence of water vapor, said catalytic system being obtained either 1) by impregnating the silicated oxides with a solution of a salt of the metals of the platinum group, followed by thermal drying and calcination, or 2) by dispersing the silicated oxides in an organic solvent and then reacting them, in a carbon monoxide atmosphere or in an inert atmosphere, with solutions of said one or more compounds of metals of the platinum group.
