Abstract:

采用浸渍法制备了Cu-Mn/γ-Al2O3、Cu-Mn/TiO2新型催化剂,研究了在不同温度、不同气体流速下对甲醛的催化活性以及50h下催化剂的稳定性,并与Cu-Mn复合氧化物催化剂进行对比。结果表明γ-Al2O3、TiO2与Cu-Mn之间的协同作用提高了催化剂对甲醛的催化活性,且Cu-Mn/γ-Al2O3在150℃可以实现甲醛的完全去除,比Cu-Mn/TiO2和Cu-Mn复合氧化物催化剂分别低80℃和140℃。3种催化剂的甲醛去除率随气速的增加而下降,且变化大小顺序为Cu-Mn/TiO2>Cu-Mn/γ-Al2O3>Cu-Mn复合氧化物。50h后Cu-Mn/γ-Al2O3和Cu-Mn复合氧化物催化剂去除率仍为100%,Cu-Mn/TiO2去除率在94%以上。采用XRD、BET和SEM-EDS等技术手段对制备的Cu-Mn/TiO2、Cu-Mn/γ-Al2O3和Cu-Mn复合氧化物进行了表征。
