随着项目的推进，催化剂采购提上日程。通过对烟台ECS催化剂的详细了解，

As the project progresses, catalyst procurement is on the agenda. Through a detailed understanding of the Yantai ECS catalyst, we believe that the use of PPd-47 has no significant difference in the tail gas reaction and the use of PPt-47. Therefore, considering the price factor, we want to use PPt-47 to replace PPd-47. The effect of PPd-47 used before meets the emission requirements. Please confirm whether it will affect the performance test. WH can consider adding more PPt-47 to the existing catalyst addition.

As the project progresses, catalyst procurement is on the agenda. Through a detailed understanding of Yantai ECS catalyst, we believe that the use of PPd-47 for exhaust gas reaction and the use of PPt-47 is not significantly different, so considering the price factor we would like to use PPt-47 instead of PPd-47. The previously used PPd-47 effect meets emission requirements. To confirm that there is an impact on performance testing, WH may consider adding some PPt-47 to the addition of existing catalysts.

随着项目的推进，催化剂采购提上日程。通过对烟台ECS催化剂的详细了解，我方认为使用PPd-47对于尾气反应与使用PPt-47没有明显差别，所以考虑价格因素我方想要使用PPt-47来替代PPd-47。之前使用的PPd-47效果符合排放要求。请确认是否对性能测试有影响，WH可以考虑在现有催化剂加入量的基础上多加一些PPt-47。<br>
