Abstract
Disclosure is made of a specific process for producing activated carbon in spherical form, starting with organic polymer spherules based on styrene and divinylbenzene, wherein said polymer spherules contain chemical groups leading to the formation of free radicals and thus to cross-linkages by their thermal decomposition, in particular sulfonic acid groups. Furthermore, various application purposes for the thus-produced activated carbon spherules are named.
