| 中文摘要: |
| 针对现有二元、三元针织和平织铂催化剂存在铂耗高、铂用量大和成本高等问题，通过对氨氧化催化剂系统细化分区，科学合理配置贵金属量、合金比例和丝径，综合考虑氨氧化反应影响因素，设计最优化的双功效铂催化剂(DEC)系统。DEC系统的铂含量大大减少，降低损耗40%~50%，整体催化剂系统降低成本25%~35%。 |
| 英文摘要: |
| To solving the problems of high consumption of Pt, the large filling amount of Pt and high cost, an optimum DEC Pt catalyst system was designed by scientifically and reasonably determine the amounts of precious metals, the metal proportion in the alloy and the diameter of the wire, and also the influence factors on the ammonia oxidation reaction. Using the DEC catalyst system, the content of Pt was significantly reduced. The loss of Pt was reduced to 40%~50% and the cost in the whole catalyst system was reduced to 25%~30%. |
