Active Macro Porous Ring
it is a macro porous raschig ring shaped active toping media with NiMo metal impregnated to filter fouling particles, like iron sulphide gums presented in the feed stream to the reactor, it is also used for pressure drop relief and distribution optimization, the material which is produced from a specially formulated alumina material and manufactured under strict controlled conditions ensuring the following properties:

High temperature resistance
High thermal shock resistance
Eliminate particulates and iron sulphide gum formation
Initial de-metallization
Uniform roundness to minimize pressure drop
High crushing strength.
High void space: 50%.

Active Macro Porous Ring provides high tortuous pathways, which trap foulants and particulates from feedstock as it passes through the material.

Active Macro Porous Ring is a cost-effective material with high particulate capacity for pressure drop control.
