The removal of carbon monoxide is a practical method that can have  a great potential for reducing concentrations down to tolerant levels.

In this study we present our results regarding the preparation of hopcalite catalysts by a new method, a combination from precipitation and redox method. The samples were investigated using micro activity equipment, for carbon monoxide oxidation in different reaction conditions (temperature in range 25-80 C, pressure 0.2-1 bar, various initial CO concentrations). The experiments showed that the CO conversion is increasing with pressure increasing and temperature decreasing. Also, the incorporation of potassium as a promoter to hopcalite was found to have a significant influence on the CO adsorption.

The prepared hopcalite catalyst exhibited steady performance in the micro activity reactor and showed over 80% CO conversion after 60 hours, reducing CO content down to residual contents. After 72 hours the performances decreases steadily to about 50%.
