薯渣的开发和利用

Production of Activated Carbon Fiber from Tubers Residue

通过利用薯渣经过预氧化处理、碳化和活化等工艺条件试验 ,得到了薯渣开发成活性碳纤维的最佳工艺条件 :薯渣经碱化 ,低含水状态下 30 0℃气氛碳化 ,碳化产物用浓度为 35 %的ZnCl2 处理 ,80 0℃活化 ,所得活性碳纤维对水中苯酚的吸附达 90

Tubers residue was made into activated carbon fiber (ACF) by a series of processes: carbonization at 300℃ for 30 minutes after being alkalized to remove soluble low molecular composites; activation at 800℃ with ZnCl 2 as a catalyst for 30 minutes. It has been shown from the experiment that the ACF made from tubers residue has the capability of removal of more than 90% phenol in wastewater.
