Guard Bed Catalysts (pre-treaters)
Ahead of other catalyst companies, we have established a guard bed technology to protect catalyst from catalyst poisons. It is required to install guard bed catalysts upstream of the catalyst bed to capture and destroy poisons, and by the same time extend the catalyst life.
We have three different shapes of guard bed catalysts listed below.
