摘要
介绍了所研制的用于柴油机排气净化的新型稀土钙钛矿型复合金属氧化物催化剂LaMnO3/γ-Al2O3。通过发动机试验的方法研究其净化效果,并与γ-Al2O3颗粒、贵金属催化剂Pd/γ-Al2O3进行了比较。结果表明,LaM-nO/γ-AlO对CO、HC、微粒及微粒中的有机组分SOF均有化学催化净化效果,尤其是对SOF净化效果明显。
The new type lathanon-calcium-titanium compound metal oxide catalyst LaMnO3/γ-Al2O3 developed for diesel engine exhaust gas purification is introduced.Its effect is studied by engine tests and it is compared with γ-Al2O3 granule and noble metal catalyst Pd/γ-Al2O3.It is shown by comparisons that LaMnO3/γ-Al2O3 has chemical catalyzing and purifying effects on CO,HC,particulate and organic constituent SOF in particulates,especially on SOF.
