Entwicklung Kugelaktivkohle bei IBU-tec

Development example: Activated charcoal pellets

In order to expand the application range for activated charcoal as a filter medium, we have developed charcoal with various specific surfaces (BET).

Here easy handling and filtering capacity were important criteria. To date common activated charcoal powders have failed to meet these demands. Our activated charcoal pellets are convincing both from technological and economic aspects. Their peculiarity lies in the enormous inner surface and fine network of outer and inner pores and channels. This means gases can be absorbed like with a sponge.
