| 中文摘要 |
| 研制了一系列非贵金属复合氧化物催化剂,测定这些催化剂净化汽车尾气的活性和抗硫、磷、铅及析碳中毒等性能,排出了它们的活性和抗硫中毒的顺序。实验表明,ASC(Re-Mn-Pb-Cu-Cr-A-Ox/Al2O3,A助剂)催化剂具有较高的活性及较好的抗硫磷、铅及析碳中毒性能,具有较好的应用前景。 |
| 英文摘要 |
| Non-noble metal containing mixed oxide catalysts used for automobile exhaust control were investigated. Results indicated that,among the miked oxide catalysts under study, ASC(mixed oxides of rare earth, Pb, Mn, Cu, Cr, and additives) has the heighest activity and a prolonged resistence to thermal shocks, carbon deposit, and poisoning of sulphur, lead and phosphorous compounds, and therefore possesses certain prospect of application under vehicle operation conditions. |
