Characteristics
This is a product we developed jointly with Henan Provincial Chemical Institute,characteristics is as follows:
   High activity
   High strength in using
   Low bulk density
   Wide temperature scope for using
   Extreme high ability of resistant to condensation water
   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.
