甘蔗渣制备板状成型活性炭的研究

以磷酸活化法所制得的甘蔗渣粉状活性炭为原料,研究不同粘接剂种类、粘接剂添加量对板状成型活性炭性能的影响。结果表明：板状成型活性炭的体积吸附量及质量吸附量随着粘结剂添加量的增加而减小;渗透速率随着羧甲基纤维素添加量的增加而减小,随着聚乙烯醇素添加量的增加先是呈略微下降而后增加;以羧甲基纤维素为粘接剂制得的板状成型活性炭的性能较好,当羧甲基纤维素的添加量为10%时,其体积碘吸附量为418.82 mg/cm^3。

Study on Preparation of Formed Activated Carbon from Bagasse

Formed activated carbon block was prepared using powdered activated carbon prepared from bagasse with phosphoric acid activation.The influence of various preparation parameters such as the type binders and the amount of the binders was investigated.The test results showed that the iodine value of quantity adsorption and volume adsorption of formed activated carbon block decreased as ratio of binder increased,the penetration rate of formed activated carbon block decreased with increasing ratio of binder when using carboxymethylcellulose as binder,and the penetration rate first decreased a little,then increased with increasing ratio of binder when using polyvinyl alcohol as binder.The adsorption behavior of formed activated carbon block binded by carboxymethylcellulose was better;the iodine value of quantity adsorption and volume adsorption was 418.8211 mg/cm^3 on 10% of carboxymethylcellulose.
