Embodiment 1
[0042] Referring to the method in Example 1 of Chinese invention patent application CN2018109163197 (2018-08-13), 210 g of a hydantoin-substituted phenolic resin matrix was prepared, wherein the carbon content was 60% and the oxygen content was 24%.
[0043] Mix 100g of it with 126g (1.2mol) of sodium carbonate, 174g (2.3mol) of potassium chloride, 5g of sodium stearate, 5g of sodium polyacrylate and 50g of deionized water, and crush the mixture to 100-200 mesh. The mixed material is extruded into pellets with a diameter of 5mm, and then dried at 110-150°C. Put the mixed material particles into a crucible, place it in a nitrogen-protected box-type high-temperature furnace, and raise the temperature to 650 °C at a heating rate of 10 °C / min, so that the mixed material is slowly thermally decomposed to form carbonized products. Further raise the temperature to 750-800°C and keep it warm for activation for 2 hours. After the activation is completed, cool down to room temperature n...
Embodiment 2
[0045] Refer to the method in Example 1 of Chinese invention patent application CN2018109163197 (2018-08-13) to prepare 150 g of methoxy-substituted phenolic resin precipitate, wherein the carbon content is 65% and the oxygen content is 29%.
[0046] Mix 100g of it with 225g (2.1mol) of sodium carbonate, 75g (1.0mol) of potassium chloride, 2g of sodium lauryl sulfate, 3g of sodium carboxymethylcellulose and 50g of deionized water, and crush the mixture to 100- 200 mesh. The mixed material is extruded into pellets with a diameter of 5mm, and then dried at 110-150°C. Put the mixed material particles into a crucible, place in a nitrogen-protected box-type high-temperature furnace, and raise the temperature to 650 °C at a heating rate of 10 °C / min, so that the mixed material is slowly thermally decomposed to form carbonized products.
