摘要:
为了探讨纤维素对活性炭孔结构的影响,采用废茶、荞麦壳和开心果壳3种生物废弃物作为制备活性炭的原材料,利用活化剂KOH,ZnCl2,通过改变浸渍比控制活性炭的比表面积和孔结构。结果表明:利用KOH活化的活性炭最佳浸渍比均为2.0;当KOH为活化剂、浸渍比为2.0时,荞麦壳活性炭的BET比表面积和微孔孔容最大,分别达到904.8 m2·g-1和0.37 cm3·g-1,开心果壳活性炭的BET比表面积和微孔孔容分别为746.7 m2·g-1和0.31 cm3·g-1,废茶活性炭的BET比表面积和微孔孔容分别为747.8 m2·g-1和0.28 cm3·g-1。纤维素去除实验的结果表明:纤维素是影响活性炭微孔结构的主要因素。
Abstract:
In order to investigate the effect of cellulose on the pore structure of activated carbon, three types of biological waste, namely waste tea, buckwheat shell, and pistachio shell, were used as raw materials for preparing activated carbon. KOH and ZnCl2 were used as activators, and the specific surface area and pore structure of activated carbon were controlled by changing the impregnation ratio. The results show that the optimal impregnation ratio for activated carbon activated by KOH is 2.0. When KOH is used as an activator and the impregnation ratio is 2.0, the BET specific surface area and micropore volume of buckwheat shell activated carbon are the highest, reaching 904.8 m2·g-1 and 0.37 cm3·g-1, respectively, and those of pistachio shell activated carbon are 746.7 m2·g-1 and 0.31 cm3·g-1, respectively, of waste tea activated carbon are 747.8 m2·g-1 and 0.28 cm3·g-1, respectively. The results of the cellulose removal experiment show that cellulose is the main factor affecting the microporous structure of activated carbon.
