Abstract (en)
[origin: WO2007095019A2] 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.
