Activation Mechanisms

Activated carbons were prepared by chemical activation from scrap tire with two chemical reagents, NaOH and KOH. The activation consisted of different impregnation of a reagent followed by carbonization in nitrogen at 700°C. The resultant activated carbons were characterized in terms of BET surface area, methylene blue adsorption and iodine number. The influence of each parameter of the synthesis on the properties of the activated carbons was discussed, and the action of each hydroxide was methodically compared. It is the first time that preparation parameters and pore texture characteristics are simultaneously considered for two closely related activating agents of the same char precursor. Whatever the preparation conditions, it was shown that KOH led to the most microporous materials, having surface areas and adsorption properties (methylene blue adsorption and iodine number) higher than those obtained with NaOH, which was in agreement with some early works. However, the surface areas, methylene blue adsorption and iodine number obtained in the present study were much higher than in previous studies, up to 951 m2/g, 510 mg/g and 752 mg/g, respectively, using scrap tire waste char:KOH equal to 1:1. The thorough study of the way each preparation parameter influenced the properties of the final materials bought insight into the activation mechanisms. Each time it was possible; the results of scrap tire waste chemically activated with hydroxides were compared with those obtained with anthracites; explanations of similarities and differences were systematically looked for.

Methylene Blue Adsorption

Activated carbons were prepared from waste particle board (WPB) by K2CO3 activation. The effects of different parameters, such as chemical/WPB ratio, activation time and activation temperature on yield, the methylene blue adsorption, Iodine number of activated carbon were investigated. The optimum conditions were determined by the method of factor analysis and the orthogonal design as follows: activation temperature 900°C, K2CO3 (50% concentration)/ WPB 4.0, activation time 60 min. Amount of methylene blue adsorption, Iodine number, phenol adsorption, BET surface area and the yield of activated carbon prepared under optimum conditions were 82.5mg/g, 1234mg/g, 185mg/g, 1026m2/g and 30.4%, respectively.
