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 shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.
