Preparation methods of granulated and monolithic Fe-Mn catalysts on the base of ferromanganese nodules were developed. The textural, structural and strength properties of catalysts were studied. It was shown that the catalysts have a developed pore structure and high mechanical strength. The catalysts were tested in the DeSOx reaction with synthesis gas at a stoichiometric ratio SO2/(CО+H2)=0,5. The effect of the preliminary catalysts sulfidizing and geometric shape of samples (granules and monolith) on the catalytic properties were investigated. The testing showed that Fe-Mn catalysts with the oxide or sulfide form of active components are active in DeSOx reaction with synthesis gas and can selectively reduce SO2 with a conversion above 90 %.
