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.
