摘　　要：选择性催化氧化(SCO)+吸收联用技术作为一种新型脱硝技术,被广泛应用在非电力行业的脱硝领域。由于非电力行业烟气排放温度在120～200℃,因此低温脱硝催化剂的研制对SCO技术的应用有着至关重要的作用。本文以金属氧化物催化剂、贵金属催化剂、表面改性碳材料催化剂以及分子筛催化剂为研究对象,综述了低温SCO脱硝催化剂的研究进展,对下一步低温SCO脱硝催化剂的研究方向具有重要的参考价值。As a new type of denitration technology, selective catalytic oxidation（SCO） and liquid absorption combined technology is widely used to eliminate NOx in non-electrical industries. Since the non-electrical industry flue gas emission temperature is 120～200 ℃, the development of low temperature denitration catalyst plays an important role in the application of SCO. In this paper, metal oxide catalysts, noble metal catalysts, surface modified carbon material catalysts and molecular sieve catalysts were studied. All of these have important reference value for the research direction of low temperature SCO denitration catalysts.
