Spherical active carbon and preparation method thereof

The invention relates to the field of active carbon preparation, and discloses spherical active carbon and a preparation method thereof. The method comprises the following steps: (1) mixing sulfonatedasphalt and an activating agent, and carrying out spray granulation on the obtained mixed solution to obtain mixed microspheres; (2) carrying out microwave activation on the mixed microspheres to obtain active microspheres; and (3) removing impurities from the active microspheres to obtain spherical active carbon, wherein the activating agent is potassium hydroxide, and the temperature of spray granulation is 600-1000 DEG C. The preparation method is simple and rapid, and the prepared spherical active carbon has the advantages of good sphericity, large specific surface area, uniform and controllable pore diameter, uniform particle size distribution and excellent adsorption performance. 本发明涉及活性炭制备领域，公开了一种球形活性炭及其制备方法。该方法包括如下步骤：(1)将磺化沥青与活化剂混合，并将得到的混合液进行喷雾造粒，得到混合微球；(2)将所述混合微球进行微波活化，得到活性微球；(3)将所述活性微球进行除杂，得到球形活性炭；其中，所述
