摘要(Abstract):
以粉末活性炭为原料、聚乙烯醇(PVA)为粘结剂制备了成型活性炭,考察了粘结剂的比例,后处理时间,成型压力等对吸附性能和抗压强度的影响。结果表明,影响碘吸附性能的因素依次为:粘结剂的比例>后处理时间>成型压力>后处理温度;影响抗压强度的因素依次为:粘结剂的比例>后处理温度>后处理时间>成型压力;最佳制备条件为:粘结剂的比例为15%,成型压力为80MPa,后处理温度为200℃,后处理时间为30m in。
Formed activated carbon was prepared using the PVA binder and the powdered activated carbon.The effects of the binder ratio,forming pressure,post-processing time and post-processing temperature to the iodine value and the compressive strength of activated carbon were investigated.The results show that the order to influence the iodine value is binder ratio>post-processing time>forming pressure> post-processing temperature;the order to influence the compressive strength of activated carbon is binder ratio>post-processing temperature>post-processing time>forming pressure;and the optimum conditions are the binder ratio 15%,the forming pressure 80MPa,the post-processing temperature 200℃,and the post-processing time 30min.
