Abstract

Catalytically active materials were obtained by processing the red mud of the Bogorodskoye field for the treatement of gas emissions from carbon monoxide. It was found that that the use of acid leaching followed by precipitation of sparingly soluble compounds with ammonium hydroxide leads to the production of materials with an iron content of 55% by weight according to elemental analysis. The samples were found to have higher specific surface area (154.8–155.7 m2/g) and porosity (0.275–0.311 cm3/g) and higher catalytic activity in the CO oxidation reaction compared to untreated red mud. It was confirmed that impregnation of the surface of refined products with copper oxide in the amount of 5 % by mass in terms of metal significantly increases the catalytic activity.
