Abstract
Provided is a granular activated carbon that can be used for applications similar to wood-based steam-activated carbons; and also provided is a method for manufacturing the same. The granular activated carbon is obtained in the following manner. An activated carbon raw material is carbonized, and then pulverized. The pulverized product is then mixed with a calcium component, and the mixture is molded. Subsequently, the molded product is carbonized and activated, followed by washing.
