本文研究了含贱金属组分的低铂复合氧化型催化剂的制备方法,讨论了不同贱金属涂层、氧化铝涂层层数、双金属氧化物涂层以及改变载体组分等对催化剂活性的影响。通过配气评价实验,筛选出三种催化剂。它们的催化剂性能与瑞典的Kiruna催化剂相当,净化CO95％以上。净化∑CH90％以上。而其中铂含量仅为Kiruna催化剂的十分之—。 In this paper, the preparation of low-platinum composite oxide catalysts containing base metal components was investigated. The effects of different base metal coatings, alumina coating layers, bimetallic oxide coatings, and varying loadings on the catalyst activity influences. Through the gas evaluation experiment, three kinds of catalysts were selected. Their catalyst performance is comparable to Kiruna’s catalyst in Sweden, with a CO95 purity of more than 95%. Purify ΣCH90% above. The platinum content is only a tenth of the Kiruna catalyst.
