水蒸气活化法制备长柄扁桃壳基介孔活性炭的研究
Preparation of Mesoporous-activated Carbon from Amygdalus Pedunculata Shell by Steam Activation
摘要
Abstract
Activated carbon with developed mesopore were prepared from Amygdalus pedunculata shell by steam activation at different technology condition.The effects of carbonization temperature, activation temperature, activation time and steam dosage on the adsorption properties and yield of resulting activated carbon were analyzed.The results showed that the optimal activated carbon was obtained at carbonization temperature 600℃, activation temperature 850℃, activation time 60 min and steam/carbide weight ratio 6:1, whose yield, iodine value, methylene blue value, mesopore ratio, BET surface area and average pore size were 12%, 1175 mg/g, 315 mg/g, 60.9%, 1127 m2/g and 2.6 nm, respectively.Besides, the results of adsorption experiment indicated that the activated carbon prepared at the optimal conditions was promising absorbent for cephalexin, the equilibrium adsorption capacity could reach 245 mg/g after 24 h, which was higher than that of coconut shell activated carbon and walnut shell activated carbon prepared under the same conditions.关键词
