摘要： This invention provides a sort of non-noble metal com­bustion catalyst of honeycomb monolithic form. The catalyst is composed of silicate material as the first carrier, a coating of metallic oxides as the second carrier and a mixture of metallic oxides and oxides of rare earth metal as the ca­talytically active component. This invention also provides the process for its prepara­tions, which comprises immersing the carriers in a coating liquid, then drying and baking it, the features of which are that the whole process, i.e. immersing, dry­ing and baking, must be carried out at leat twice. The second carrier is obtained after the first round of immersing, drying and baking, and the catalytically ac­tive component is loaded after the second treatment so as to obtain the factual product.
