摘要：NOVELTY - Denitration catalyst comprises (wt.%) carrier (49-89.99), metallic oxide (10-50), and melamine (0.01-1). USE - Denitration catalyst. ADVANTAGE - The denitration catalyst is environment-friendly, does not produce secondary pollution, provides high denitration efficiency, energy saving and has wide application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of denitration catalyst by weighing carrier; dissolving metallic inorganic salt precursor in water at weight ratio of load metal and carrier of 0.01-0.3:1 to prepare solution with concentration of 0.01-0.15 g/ml; mixing pre-weighed carrier and metallic inorganic salt precursor at volume ratio of 1:1-2; uniformly stirring and soaking for 4-20 hours; drying 60-100 degrees C for 10-24 hours to prepare solid product; burning solid product with nitrogen; weighing melamine and dissolving in water at 80-100 degrees C to prepare melamine solution; mixing solid and melamine solution at volume ratio of 1:1-2, so that weight ratio of melamine and solid is 0.01-0.3:1; stirring mixture; and drying at 80-150 degrees C to prepare denitration catalyst.
