Oxidation of Carbon Monoxide by Oxygen on Palladium and Ruthenium Catalyst

Recently, the authors described the catalytic elimination of nitrogen oxide from crm hydrogen [1], in the course of which a secondary contamination of gas with cark dioxide occurred in a plant in Slovakia. This fact stimulated the authors to study th undesirable reaction, i.e. oxidation of carbon monoxide by oxygen. The oxidation of carbon monoxide with respect to industrial usage has been studk by Brown et al. [2]. They have, however, described neither the kinetics nor the reactic mechanism and have been mainly interested in the selection of catalyst. They ш some rare metals on a carrier as catalysts. Thus they examined platinum, rutheniui and rhodiiun. In their laboratory experiments with palladium catalyst they came aero; interesting observations. The palladium catalyst accelerates the reaction between oxy gen and hydrogen
