Abstract

Abrasion-resistant active carbon carriers or catalysts are made. To this end, an abrasion-resistant carrier is impregnated with an aqueous solution of a saccharide, the impregnated carrier is dried and the saccharide is thermally decomposed in the absence of air to active carbon which tenaciously adheres to the carrier.
