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 exhaust emission requirements. Please confirm whether it will affect the performance test. WH can consider adding more PPt-47 to the existing catalyst addition.

To confirm that there is an impact on performance testing, WH may consider adding some PPt-47 to the addition of existing catalysts.
