Method for preparing coal pitch-based activated porous carbon through melting and alkali activation of chlorate mixture

The invention discloses a method for preparing coal pitch-based activated porous carbon through the melting and alkali activation of a chlorate mixture, and belongs to the field of preparation of activated porous carbon materials. The preparation method comprises the following steps: S1, uniformly mixing a chlorate mixture with asphalt, putting the mixture into a heating furnace, carrying out heating and a heat preservation treatment in a protective atmosphere to polymerize asphalt molecules, then carrying out heating carbonization and a heat preservation treatment, cooling to the room temperature, washing, and drying to obtain porous carbon prepared by melting the chlorate mixture; and S2, uniformly mixing the porous carbon obtained in the step S1 with sodium hydroxide, putting the mixture into a heating furnace, carrying out heating activation and a heat preservation treatment in a protective atmosphere, cooling to the room temperature, washing, and drying to obtain the asphalt-basedactive porous carbon.
