Embodiment 1
[0028] (1) The petroleum coke raw material is placed in a pulverizer for preliminary grinding and sieving treatment to obtain pretreated petroleum coke powder with a size of 1-20 μm.
[0029] (2) Weigh urea and petroleum coke powder (molar ratio 5:1) and mix them in a stainless steel ball mill tank, add zirconia balls (3mm in diameter, 40g), assemble them in a planetary ball mill, set the speed at 400rpm, and run the ball mill every 5 minute interval, the interval time is 2.5 minutes, and the total running time is 12 hours.
[0030] (3) Put the ball-milled material into a quartz boat and place it in a tube furnace with nitrogen as a protective gas. The initial temperature is room temperature, and the temperature is raised to 1000°C at 5°C / min, and kept at this temperature for 2 hours, and then After natural cooling down to room temperature, the obtained black solid is the porous carbon material derived from petroleum coke.

Embodiment 2
[0037] (1) The petroleum coke raw material is placed in a pulverizer for preliminary grinding and sieving treatment to obtain pretreated petroleum coke powder with a size of ~1-20 μm.
[0038] (2) Weigh melamine and petroleum coke powder (molar ratio 3:1) and mix them in a stainless steel ball mill tank, add zirconia balls (3mm in diameter, 30g), assemble them in a planetary ball mill, set the speed at 500rpm, and run the ball mill every 5 minute interval, the interval time is 2.5 minutes, and the total running time is 24 hours.
[0039] (3) The material after ball milling was put into a porcelain ark, placed in a tube furnace with argon as a protective gas, the initial temperature was room temperature, the temperature was raised to 900 °C at 10 °C / min, and kept at this temperature for 2 hours, Then naturally cool down to room temperature to obtain a porous carbon material.
[0040](4) Put the porous carbon material into a porcelain ark and place it in a muffle furnace. The i...
Embodiment 3
[0042] (1) The petroleum coke raw material is placed in a pulverizer for preliminary grinding and sieving treatment to obtain pretreated petroleum coke powder with a size of ~1-20 μm.
[0043] (2) Weigh urea and petroleum coke powder (molar ratio 15:1) and mix them in a stainless steel ball mill tank, add zirconia balls (3mm in diameter, 30g), assemble them in a planetary ball mill, set the speed at 400rpm, and run the ball mill every 10 minute interval, the interval time is 5 minutes, and the total running time is 12 hours.
[0044] (3) The material after ball milling was put into a porcelain ark, placed in a tube furnace with nitrogen as a protective gas, the initial temperature was room temperature, the temperature was raised to 800 °C at 5 °C / min, and kept at this temperature for 4 hours, and then Naturally cooling down to room temperature, the porous carbon material is obtained.
[0045] (4) Put the porous carbon material into a porcelain ark and place it in a muffle fur...
