DuraTop^® special reformed packings are used among other things for covering catalyst beds. DuraTop^® special reformed packings can be added onto the top ball layer or even replace the top ball layer. As the top layers on the catalyst beds DuraTop^® special reformed packings offer the following advantages:

• low pressure drop because of large free-gap volume
• good pre-distribution of the liquid and gaseous media, even before they reach the catalyst bed, due to open internal structure of the DuraTop^® special reformed packing
• the large specific surface increases the retention of any particulate impurities of the media before they reach the catalyst bed.
