Inert Topping Media
it is inert ceramic dome shaped tablet with seven holes are produced from a specially formulated silica / alumina material and fired under strict controlled conditions ensuring the following properties:

High temperature resistance
High thermal shock resistance
Uniform roundness to minimize pressure drop
High crushing strength.
High void space.

Inert Topping Media as bed hold-down material at the top of the catalyst bed can provide pressure drop relief, optimize the flow distribution, capture of particulates and other contaminants in the feed.
