Abstract
A pot furnace low-temperature calcination process may ensure that, by controlling the flame path temperature and discharge speed of the pot furnace, that the range of the temperature at which the petroleum coke is calcined in the pot is from 1150° C. to 1220° C., and that the discharge speed is 10 to 20% higher than the normal discharge speed and reaches 110˜120 kg/h, reducing the amount of desulfurization of the petroleum coke during the calcination so that the true density of the calcined coke is between 2.05 and 2.07 g/cm3.
Claims5
A pot furnace low-temperature calcination method comprising:
- providing a pot;
- providing a flame path proximate to the pot such that heat from the flame path heats the pot;
- controlling a flame path temperature and discharge rate of the pot furnace such that petroleum coke is calcined in the pot at a temperature range from 1150° C. to 1220° C., the discharge rate of the pot being controlled to be 110˜120 kg/h;
- and
- reducing an amount of desulfurization of the petroleum coke during calcination so that true density of the calcined coke is between 2.05 and 2.07 g/cm3;
- wherein the flame path temperature is controlled to be less than 1250° C.
