The use of catalytic neutralization for the purification of harmful emissions from ship power plants can significantly reduce the negative impact of exhaust gases on all environmental objects. The attractiveness of the proposed method lies in the possibility of selecting the appropriate composition of the catalytic material depending on the required degree of purification.The functional properties of catalytic materials are largely determined by the qualitative and quantitative composition of the material used, as well as the conditions of its operation - the temperature regime.In order to determine the acceptable composition of the catalytic converter material, we made an analyses of materials of various compositions. The optimum degree of purification was achieved on materials containing valuable components (rhodium, iridium, palladium). However, the issue of reducing the treatment system cost is important. So, the possibility of replacing such metals with ore grindings (bastnesite, loparite) has been studied in the paper.
