Abstract

The invention relates to a mechanically stable, porous shaped activated carbon article having a first three-dimensional framework structure based on carbonized resin, a second three-dimensional inorganic framework structure comprising ceramic material and/or baked refractory material, and binding agent, as well as activated carbon particles, in which the first and second framework structures penetrate each other at least partially and the activated carbon particles are fixed to the framework structures. The invention also relates to a process for the production of such a shaped activated carbon article and to the use thereof.
