Abstract
The invention relates to a method for the selective catalytic oxidation of carbonmonoxide (CO) in H2-rich, CO2- and H2-containing gases in the presence of a noble metal catalyst on an alumina carrier with the addition of air as oxidizing agent. According to the invention, with this method α-AL2O3 carrier can be less than 25 m2/gram. The noble metal can be ruthenium or platinum and preferably a combination of ruthenium (Ru) and platinum (Pt), the sum of the quantities of RU and Pt being less than or equal to 1.0% (m/m).
Claims7
A method for the selective catalytic oxidation of carbon monoxide comprising:
- catalytically oxidizing a quantity of carbon monoxide in H2-rich, CO2- and H2O-containing gases in the presence of a noble metal catalyst on an α-Al2O3 carrier with the addition of a quantity of air as oxidizing agent wherein the noble metal is a mixture of ruthenium and platinum.
