The application of the rare earth three way catalytic technology on the purifying of the motorcar gas

DING Ya (Guizhou Province Economic and Trade Committee, Economic & Technical Market Development Center, Guiyang 550001,China)  
It has been proved that the perofskite structural oxide containing rare earth is a kind of active catalyst in terms of the reducing of the carbon dioxide,hydrocarbon and oxides of nitrogen. The article mainly meditates the purifying effectiveness and the economic rationality from the direction of making the rare earth catalyst replaces the precious metal catalyst, through the choosing of the rare earth catalytic carrier and the designing of the purifier's basic structure, the subject can be incarnated in two aspects:one is the rare earth's chemical stability during the the process of the redox reaction and the purifying effectiveness on the carbon dioxide、hydrocarbon and oxides of nitrogen; another is the catalyst carrier and the purifier can fulfill the needs of cleansing,denoising,lowing the air lock,fortifying the intensity,radiating the heat,lowering the elevated temperature etc., so can it achieve the technology's economic rationality.
