| titleOfInvention | Method for modifying activated carbon adsorbent |
| abstract | The invention discloses a method for modifying an activated carbon adsorbent, and belongs to the technical field of adsorbent modification. Placing activated carbon cleaned by water and subjected to impurity removal in a high-temperature high-pressure reaction kettle, introducing carbon dioxide, heating to a carbon dioxide supercritical state, treating for 1-60 min to obtain pretreated activated carbon, opening a pressure release valve, and collecting the carbon dioxide; and (3) placing the pretreated activated carbon in a subcritical state or a supercritical state of water for treating for 1-30 min, cooling to a temperature not higher than 100 ℃, opening a pressure release valve, and quickly reducing the pressure to separate gas, liquid and solid, wherein the solid is the modified activated carbon adsorbent. The method has the advantages of simple operation, no pollution, high modification efficiency and direct discharge of residual liquid. |
