Abstract

The invention relates to a method for producing spherical activated carbon, wherein polymer globules, which comprise thermally decomposing chemical groups, are carbonized. It is characterized by that during the carbonization, a supplier of free radicals is added to the polymer globules, the supplier of free radicals forming free radicals, which are different from the free radicals that are generated by the decomposition of the chemical groups.
