Application : Shaped Ring
Type : Inert Ceramic
Shape : Shaped Rings

ACT 070 has been developed to extend cycle length of units pressure drop due to particulate deposition or top bed crust formation. ACT 070 replaces ineffective inert balls used for bed hold-down at the top of catalytic reactors in liquid phase or vapor phase service, such as refinery hydrotreating and other similar applications.


The bed topping is a highly inert ceramic incorporating a special penta-ring shape with a high void fraction to provide an efficient capture of particulates and other contaminants in the feed. ACT 070 is one of the successive stages in Axens system for pressure drop control.


The ceramic penta-rings provide a high void volume and a large void gap to trap particulates and mitigate pressure drop build-up.
