| 中文摘要: |
| Pd/Al2O3催化剂因其优异的甲烷燃烧催化活性而被广泛应用于消除和控制燃气发动机污染物的排放。通过综述近20年来Pd/Al2O3甲烷燃烧催化剂的研究进展，系统地讨论了活性组分、助剂以及制备方法等因素对Pd/Al2O3催化剂的催化活性、热稳定性、耐水及耐硫中毒能力的影响，并提出利用新型制备技术制备掺杂非金属助剂的双贵金属或多贵金属活性组分的Pd/Al2O3催化剂是未来低成本高性能甲烷燃烧催化剂的开发方向。 |
| 英文摘要: |
| Pd/Al2O3 catalysts are widely used to reduce and control pollutants emissions from gas engines due to their excellent catalytic activity for methane combustion. By reviewing the research progress of Pd/Al2O3 methane combustion catalysts in the past 20 years, the effects of active components, additives and preparation methods on the catalytic activity, thermal stability, anti-water and anti-sulfur poisoning ability of Pd/Al2O3 catalysts were systematically discussed. It is proposed that the use of new preparation technology to prepare Pd/Al2O3 catalysts with dual-precious metal or multi-precious metal active components doped with non-metallic additives is the future development direction for low-cost and high-performance methane combustion catalysts. |
