摘　　要：以复合稀土氧化物的γ-Al2O3为催化剂载体,将负载钯的超微粒子金属铁、钴、镍与γ-Fe2O3粉体混合成型焙烧制成催化剂。研究了复合稀土氧化物对γ-Al2O3表面积的影响,通过催化剂老化实验、丙烷化合物起燃温度检测和对模拟汽车尾气中丙烷、CO及NOx等物质的转化性能的研究,表明该型催化剂各性能较好。Loading-Pd ultramicron particle metals Fe. Co, Ni and γ-Al2O3 which had been mixed efficiently in γ-Al2O3 were formed and calcination and the catalyst was prepared. Effect of rare earths on the surface areas of γ-Al2O3 was studied. The results showed that this catalyst had excellent catalytic properties by catalyst-aging, by testing ignition temperature of propane and by investigating properties of the catalyst for conversion of propane, CO and NOx.
