Abstract

The invention relates to a method for producing spherical activated carbon from divinyl-benzene or styrene-divinyl-benzene polymer-based polymers in gel or macroporous form, by sulfonating the polymer with sulfuric acid and stirring the reaction material at a sulfonating temperature of 200 to 250 °C, for 20 to 90 minutes. The ratio H2SO4:polymer, calculated as pure substances, is 1.4:1 to 3:1 at the beginning of the sulfonation. The heating rate until the sulfonating temperature is reached is 5 to 20 K/min. The sulfonated polymer is then cooled to a temperature of < 50 °C and pyrolised by heating the product to a temperature of 250 °C with a heating rate of 5 to 15 K/min. The temperature is maintained at 250 °C for 30 minutes. The product is then further heated to 330 °C with a heating rate of 2 to 10 K/min, and subsequently to a temperature of 750 to 900 °C with a heating rate of 50 K/min. The product is maintained at the maximum temperature for 5 to 10 minutes.
