摘要：工业烟气一氧化碳(CO)的催化净化对高活性耐久结构型催化剂的需求日渐迫切。将多元金属氧化物催化剂涂覆到堇青石蜂窝载体上制得了一系列结构型催化剂。结果表明,硅溶胶与热风吹动干燥可促进粉末催化剂均匀致密平铺在载体表面,提高了结构型催化剂的抗脱落性能与催化性能,优选催化剂超声60 min后的涂层脱落率为0.97%;在7500 h^(–1)空速、1%CO、8%水蒸气含量、110℃可达到99%CO催化效率,并在72 h内保持稳定;在实际烧结烟气条件下,720 h后CO催化效率可稳定在86%以上。
High activity and durable structural catalysts are increasingly needed for carbon monoxide (CO) catalytic removal of industrial flue gas.A series of structural catalysts were prepared by coating polymetallic oxide catalyst on cordierite honeycomb supports.The results showed that silica sol and hot air drying could promote the powder catalyst to evenly and compactly spread on the surface of the support,and improve the anti-shedding performance and catalytic performance of the structural catalyst.The coating shedding rate of the optimized catalyst after 60 min of ultrasonic vibration was 0.97%.The catalytic efficiency of 99%CO can be achieved at 7 500h^(-1) hspace speed,1%CO,8%water vapour content and 110℃,and remains stable within 72 h.The CO catalytic efficiency can be stabilized above 86%after 720 h in actual sintering flue gas condition.
