Catalytic system for catalytic partial oxidation processes with a short contact time

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. 本发明涉及用于具有短接触时间的催化部分氧化方法的催化体系。具体而言，本发明涉及包含至少两个催化区的催化体系，其中至少个区排他性地含有种或多种选自由铑、钌、铱、钯和铂组成的集合的贵金属且至少另区含有镍，所述催化体系的特征在于至少个排他性地含有选自由铑、钌、铱、钯和铂组成的集合的贵金属的区总是与至少个含有镍的区不同，但与所述至少个含有镍的区接触。可能将种或多种选自由铑、钌、铱、钯和铂组成的集合的金属加到所述个或多个包含镍的催化区中。
