Embodiment 1
[0026] Prepare a coke sample C1 with a particle size of 19-21 mm, put it into a heating furnace for heating, record the weight w1 of the coke sample into the furnace as 200 g, and adopt segmental heating during the heating process, and the heating rate between room temperature and 300 °C is 15 °C / min; The heating rate in the interval from 300°C to 800°C is 12°C / min; the heating rate from 800°C to the final temperature is 10°C / min, and the final temperature is 1600°C. After heating to the final temperature, keep the constant temperature for 2 hours. During the heating process The coke samples were protected by nitrogen gas. Then the heated coke sample was cooled to room temperature and taken out, weighed and recorded, and the furnace weight w2 was 181g. Put the coke sample cooled to room temperature into a type I drum at 20 rpm for 30 minutes, and then weigh the coke with a particle size below 10mm, w3, to be 36g.
Embodiment 2
[0028] Prepare a coke sample C1 with a particle size of 19-21 mm, put it into a heating furnace for heating, record the weight w1 of the coke sample into the furnace as 200 g, and adopt segmental heating during the heating process, and the heating rate in the range from room temperature to 300 °C is 20 °C / min; The heating rate in the interval from 300°C to 800°C is 10°C / min; the heating rate from 800°C to the final temperature is 8°C / min, and the final temperature is 1500°C. After heating to the final temperature, keep the constant temperature for 2 hours. During the heating process The coke samples were protected by nitrogen gas. Then the heated coke sample was cooled to room temperature and taken out, weighed and recorded, and the furnace weight w2 was 178g. Put the coke sample cooled to room temperature into a type I drum at 20 rpm for 30 minutes, then weigh the coke with a particle size below 10mm w3 to be 32g.
Embodiment 3
[0030] Prepare a coke sample C1 with a particle size of 19-21 mm, put it into a heating furnace for heating, record the weight w1 of the coke sample into the furnace as 200 g, and adopt segmental heating during the heating process, and the heating rate between room temperature and 300 °C is 18 °C / min; The heating rate in the interval from 300°C to 800°C is 15°C / min; the heating rate from 800°C to the final temperature is 9°C / min, and the final temperature is 1400°C. After heating to the final temperature, keep the constant temperature for 2 hours. During the heating process The coke samples were protected by nitrogen gas. Then the heated coke sample was cooled to room temperature and taken out, weighed and recorded, and the furnace weight w2 was 184g. Put the coke sample cooled to room temperature into a type I drum at 20 rpm for 30 minutes, and then weigh the coke with a particle size below 10mm, w3, to be 28g.
