The invention belongs to the technical field of low-temperature SCR denitration, and in particular relates to a Ce-Mn composite material catalyst for a low-temperature SCR denitration reaction and a preparation method thereof. The carrier is γ-Al 2 O 3 , and the active component is a mixture of manganese oxide, cerium oxide and Ce-Mn composite oxide, wherein: cerium and manganese respectively account for 1% to 15% of the mass of the carrier; The oxide is MnO 2 , and the oxide of cerium is CeO 2 . The Ce-Mn composite material catalyst for the low-temperature SCR denitration reaction of the present invention is applied to the SCR denitration reaction, and at a temperature of 120-190° C. and a space velocity of 5,000-30,000 h -1 , the single-pass NOx conversion rate can reach more than 88%, Has good low temperature denitration performance. |
