The present invention relates to a catalytic system comprising at least two catalytic zones of which at least one zone exclusively contains one or more noble metals selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium and Platinum and at least another zone contains Nickel, said catalytic system characterized in that at least one zone exclusively containing noble metals selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium and Platinum is always distinct but in contact with at least one zone containing Nickel. One or more metals selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium and Platinum are possibly added to the catalytic zone or zones comprising Nickel.

1. A catalytic system, comprising: a first catalytic zone comprising at least one noble metal selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium, and Platinum; anda second catalytic zone comprising Nickel and at least one metal selected from the group consisting of Rhodium,
1. A catalytic system, comprising: a first catalytic zone comprising at least one noble metal selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium, and Platinum; anda second catalytic zone comprising Nickel and at least one metal selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium, and Platinum,wherein the first catalytic zone is distinct but in contact with the second catalytic zone comprising Nickel and at least one metal selected from the group consisting of Rhodium, Ruthenium, Iridium, Palladium, and Platinum, andsaid first catalytic zone does not contain Nickel. 2. The catalytic system of claim 1, wherein the second catalytic zone comprises Palladium or Platinum. 3. The catalytic system of claim 1, wherein the first catalytic zone comprises Rhodium and the second catalytic zone comprises Nickel and Rhodium. 4. The catalytic system of claim 2, wherein the first catalytic zone, the second catalytic zone, or both comprise Rhodium. 5. The catalytic system of claim 1, wherein the first and second catalytic zones are arranged to form a catalytic bed. 6. The catalytic system of claim 1, wherein the noble metal amount ranges from 0.2% to 10% weight, with respect to the total catalyst weight. 7. The catalytic system of claim 6, wherein the noble metal amount ranges from 0.5% to 2% weight, with respect to the total catalyst weight. 8. The catalytic system of claim 1, wherein the Nickel amount ranges from 0.5% to 20% weight, with respect to the total catalyst weight. 9. The catalytic system of claim 8, wherein the Nickel amount ranges from 2% to 10% weight, with respect to the total catalyst weight. 10. The catalytic system of claim 5, wherein each of said first catalytic zone and said second catalytic zone is in the form of metallic pellets, wherein each of said at least one noble metal and said Nickel is supported on spheres of α-alumina. 11. The catalytic system of claim 1, wherein the noble metal amount ranges from 0.2% to 10% weight, with respect to the total catalyst weight, and the Nickel amount ranges from 0.5% to 20% weight, with respect to the total catalyst weight. 12. The catalytic system of claim 1, wherein the noble metal amount ranges from 0.5% to 2% weight, with respect to the total catalyst weight, and the Nickel amount ranges from 2% to 10% weight, with respect to the total catalyst weight. 13. The catalytic system of claim 3, wherein the Rhodium amount ranges from 0.2% to 10% weight, with respect to the total catalyst weight, and the Nickel amount ranges from 0.5% to 20% weight, with respect to the total catalyst weight. 14. The catalytic system of claim 3, wherein the Rhodium amount ranges from 0.5% to 2% weight, with respect to the total catalyst weight, and the Nickel amount ranges from 2% to 10% weight, with respect to the total catalyst weight. 15. The catalytic system of claim 10, wherein the noble metal amount ranges from 0.2% to 10% weight, with respect to the total catalyst weight, and the Nickel amount ranges from 0.5% to 20% weight, with respect to the total catalyst weight. 16. The catalytic system of claim 10, wherein the noble metal amount ranges from 0.5% to 2% weight, with respect to the total catalyst weight, and the Nickel amount ranges from 2% to 10% weight, with respect to the total catalyst weight. 17. The catalytic system of claim 15, wherein the first catalytic zone comprises Rhodium and the second catalytic zone comprises Nickel and Rhodium. 18. The catalytic system of claim 16, wherein the first catalytic zone comprises Rhodium and the second catalytic zone comprises Nickel and Rhodium.
