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。
The composite rare earth oxide γ-Al2O3 as a catalyst carrier, the palladium-supported ultrafine particles of metal iron, cobalt, nickel and γ-Fe2O3 powder mixed molding roasted catalyst. The effect of composite rare earth oxides on the surface area of γ-Al2O3 was studied. The catalyst aging experiment, the ignition temperature of propane compounds and the conversion of propane, CO and NOx in the tail gas were studied. better.
