CATALYTIC PARTIAL OXIDATION WITH TWO CATALYTICALLY-ACTIVE METALS

摘要

The invention relates to a catalyst or a precursor thereof in the form of a fixed arrangement or in the form of catalyst (precursor) particles, wherein the fixed arrangement or the particles comprise(s) at least two layers, the first layer comprising as a catalytically active metal or precursor thereof rhodium or a rhodium compound and the second layer comprising as a catalytically active metal or precursor thereof iridium, osmium or platinum or a compound thereof. The invention further relates to the use of the catalyst, especially in a process for the catalytic partial oxidation of a hydrocarbonaceous feedstock.
