摘要： 以粉状白酒糟物理活化炭为原料，以羧甲基纤维素(CMC)、煤焦油和酒糟活性炭灰分碱处理溶出液为粘结剂，研究了高含Si灰生物质粉末活性炭的成型方法. 结果表明，单独以CMC和煤焦油作为粘结剂，在4.0 MPa成型压力下所制成型活性炭的侧压强度达120 N/cm，但其碘吸附能力低于400 mg/g. 利用酒糟基活性炭灰碱处理溶出液，仅添加少量CMC成型的活性炭达到相同侧压强度，吸附能力达600 mg/g以上，明显高于仅添加CMC或煤焦油成型的活性炭，以及原活性炭粉. 对成型活性炭进行了红外光谱、XRD及SEM表征，分析了其粘结机理.

Abstract: The activated carbon (AC) made from distilled spirits lees has high content of Si-rich ash. The molding methods of such AC by using carboxymethyl cellulose (CMC), coal tar and leaching solution from alkali treatment of the high-Si ash AC as the binder were investigated. The results showed that using only CMC or coal tar as the binder, the compressive strength of molded AC at a pressing pressure of 4 MPa reached the expected 120 N/cm, but the iodine adsorption capacity was lower than 400 mg/g. When using the silica alumina sol made with the leaching solution as the binder, mixing silica alumina sol and a small amount of CMC allowed the molded AC to have the satisfied compressive strength, while its adsorption capacity of iodine reached over 600 mg/g, higher than the AC molded with CMC or coal tar only, and original AC powder. The molded AC was characterized by FT-IR, XRD and SEM, and its binding mechanism analyzed.
