Embodiment 1
[0017] A carbonization processing method for corn stalks, comprising the following steps:
[0018] (1) Clean the harvested corn stalks from sludge and impurities, soak them in a sodium sulfite solution with a mass concentration of 0.7% for 2 hours, then take them out and drain the water, dry them at 110°C for 4 hours, cool them down to 30°C, and crush them into granules The diameter is between 1-2mm;
[0019] (2) Put the pulverized material into the carbonization furnace, raise the temperature to 380°C at a rate of 8°C / min, keep warm and carbonize for 1.5 hours, then continue to heat up to 550°C at a rate of 6°C / min, keep warm and carbonize for 30 minutes, Finally, the temperature was lowered to 400°C at a rate of 10°C / min, kept warm and carbonized for 20 minutes, and taken out after natural cooling in the furnace to obtain carbonized materials;
[0020] (3) Put the carbonized material into the tube furnace, feed nitrogen, raise the temperature to 210°C, activate for 5 hours,...

[0026] A carbonization processing method for corn stalks, comprising the following steps:
[0027] (1) Clean the harvested corn stalks from sludge and impurities, soak them in a sodium sulfite solution with a mass concentration of 0.8% for 2.5 hours, then take out and drain the water, dry them at 112°C for 4.5 hours, cool down to 33°C, and crush them into grains The diameter is between 1-2mm;
[0028] (2) Put the pulverized material into the carbonization furnace, raise the temperature to 390°C at a rate of 8.5°C / min, keep warm and carbonize for 1.8 hours, then continue to heat up to 580°C at a rate of 6.5°C / min, keep warm for 35 minutes, Finally, the temperature was lowered to 410°C at a rate of 11°C / min, kept warm and carbonized for 25 minutes, and taken out after natural cooling in the furnace to obtain carbonized materials;
[0029] (3) Put the carbonized material into the tube furnace, feed nitrogen, raise the temperature to 220°C, activate for 6 hours, stop heating and ...
Embodiment 3
[0035] A carbonization processing method for corn stalks, comprising the following steps:
[0036] (1) Remove the sludge and impurities from the harvested corn stalks, soak them in a sodium sulfite solution with a mass concentration of 0.9% for 3 hours, then take out and drain the water, dry them at 115°C for 5 hours, cool down to 35°C, and crush them into granules The diameter is between 1-2mm;
[0037] (2) Put the pulverized material into the carbonization furnace, raise the temperature to 400°C at a rate of 9°C / min, keep warm and carbonize for 2.0 hours, then continue to heat up to 600°C at a rate of 7°C / min, keep warm and carbonize for 40 minutes, Finally, the temperature was lowered to 420°C at a rate of 12°C / min, kept warm for 30 minutes, and then taken out after natural cooling in the furnace to obtain carbonized materials;
[0038] (3) Put the carbonized material into the tube furnace, feed nitrogen, raise the temperature to 230°C, activate for 7 hours, stop heating a...
