Abstract:
Activated charcoal (AC) is a popularly used material in environmental treatment. In this study, the effect of the carbonization condition by controlling the conversion rate of the carbonaceous skeleton on the reactivity of the Cashew nutshells (CNS) has been surveyed. The charcoal (CC) samples obtained from the carbonization were activated at 850oC using the steam. The obtained AC had the good BET surface area of 1171 m2/g and a total pore volume of 0.7 cm3/g. In comparison with parameters of the step with the single heating rate and only once, both BET surface area and total pore volume increased to 130% and 133%, respectively. Additionally, The results also showed the effectiveness of controlling the conversion rate of the carbonaceous skeleton in the CNS residue. This fundamental research provides a new concept of a multi-method for AC production.
