ACTIVATED CARBON BEADS AND METHODS OF MAKING THEM

ACTIVATED CARBON BEADS AND METHODS OF MAKING THEM

Activated carbon beads are disclosed made from resol beads prepared in high yield by reaction of a phenol with an aldehyde, with a base as catalyst, in the presence of a colloidal stabilizer, and optionally a surfactant. The resol beads are then optionally thermally treated, and afterward carbonized...

Zusammenfassung:Activated carbon beads are disclosed made from resol beads prepared in high yield by reaction of a phenol with an aldehyde, with a base as catalyst, in the presence of a colloidal stabilizer, and optionally a surfactant. The resol beads are then optionally thermally treated, and afterward carbonized and activated to obtain the activated carbon beads.
