1.High activity
2.High strength in using
3.Low bulk density
4.Wide temperature scope for using
Description:
Characteristics is as follows:
1. High activity
2. High strength in using
3. Low bulk density
4. Wide temperature scope for using
5. Extreme high ability of resistant to condensation water
6. Low sulfur content in catalyst' body, special time for releasing sulfur can be saved in initial start of large scale synthetic ammonia plant in which high temperature converter is connected to low temperature converter directly.
