Low temperature NH₃-SCR performance and mechanism of Mn and Fe supported CeCO₃F-monazite catalysts.

ABSTRACT: The group has shown that Baiyun Ebo rare earth concentrate has excellent performance in NH₃-SCR denitrification when used as a carrier, where rare earth elements are mainly present in cerium fluorocarbon ore (CeCO₃F) and monazite (CePO₄) mineral phases. In this paper, a new low-temperature NH₃-SCR catalyst of Mn-Fe/CeCO₃F-monazite was prepared by an impregnation method, using synthetic CeCO₃F and purified monazite as carriers. By exploring its denitrification performance and mechanistic analysis, it provides theoretical guidance for the use of rare earth concentrates as low-temperature NH₃-SCR catalysts. Our previous studies have determined the optimum loading of Fe, so this paper needs to be investigated for the
