ABSTRACT:
The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3% by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.
