Abstract

The use of rubber-seed shell as a raw material for the production of activated carbon with physical activation was investigated. The produced activated carbons were characterized by Nitrogen adsorption isotherms, Scanning electron microscope, Thermo-gravimetric and Differential scanning calorimetric in order to understand the rubber-seed shell activated carbon. The results showed that rubber-seed shell is a good precursor for activated carbon. The optimal activation condition is: temperature 880 °C, steam flow 6 kg h−1, residence time 60 min. Characteristics of activated carbon with a high yield (30.5%) are: specific surface area (SBET) 948 m2 g−1, total volume 0.988 m3 kg−1, iodine number of adsorbent (qiodine) 1.326 g g−1, amount of methylene blue adsorption of adsorbent (qmb) 265 mg g−1, hardness 94.7%. It is demonstrated that rubber-seed shell is an attractive source of raw material for producing high capacity activated carbon by physical activation with steam.
