| 摘 要： | 以镧改性的Ce-Zr-O固溶体储氧材料和钇、锆改性的氧化铝(YSZ-Al2O3)的混合物为载体,浸渍活性组分Co3O4+Fe2O3+MnO2,以蜂窝状堇青石陶瓷材料为基体,制备了甲烷催化燃烧催化剂,考察了该催化剂老化前后的活性,并将其用于强鼓式家用天然气催化燃烧热水器. 结果表明,该催化剂具有很高的活性和稳定性. 使用此催化剂的天然气催化燃烧热水器的热效率达到101.1%, 同时烟气中CO和NOx污染物的排放浓度分别为0.014%和0.003%, 该热水器具有高效节能和环境友好双重优点.

| Abstract: | A Co_3O_4-Fe_2O_3-MnO_2 monolithic catalyst supported on a mixture of yttria-stabilized zirconia(YSZ)-Al_2O_3 and La-modified CeO_2-ZrO_2 oxygen storage material was prepared.The catalyst activity for methane combustion was measured in a microreactor,and a domestic natural gas premixed catalytic combustion fan-boiler prototype was developed on the basis of this methane combustion catalyst system.The monolithic catalyst has high activity and good thermal stability,and the natural gas premixed catalytic fan-boiler has the advantages of high thermal efficiency and low CO and NO_x emissions.Hence it is an energy saving and environmentally friendly product with high efficiency. |
