Abstract
The invention concerns high-performance adsorbents based on activated carbon of high meso- and macroporosity which are present in the form of discrete grains of activated carbon, wherein: These high-performance adsorbents are obtainable by a novel process comprising specific two-stage activation, and have, in addition to the aforementioned properties, an excellent abrasion and bursting resistance, so that they are useful for a multiplicity of different applications.
