Abstract
本申请公开了一种炭球吸附剂的制备方法，包括如下步骤：S1、将包含沥青粉末和萘的原料混合均匀后置入密闭容器中，加热反应，粉碎得到含萘沥青颗粒；S2、将包含步骤S1中得到的含萘沥青颗粒与交联剂、引发剂、表面活性剂、油性溶剂的混合物混合均匀后置入密闭容器中，加热合成，得到含萘沥青球；S3、将步骤S2中得到的含萘沥青球在真空环境下下加热改性，得到改性沥青球；S4、将步骤S3中得到的改性沥青球，加热炭化活化，得到炭球吸附剂。制备方法简单，无须经历氧化不熔化过程即可直接炭化制备沥青基活性炭球，可大大缩短炭球制备时间，节约能耗，且制备得到的炭球吸附剂杂质含量低、球形度好、富含微孔，可用做炭球吸附剂。
