The main raw material of calcined coke is petroleum coke, and high quality calcined coke is produced by calcined petroleum coke at high temperature.

After calcination at 1250℃, the moisture and volatilization of petroleum coke are removed, thus increasing the carbon content of petroleum coke, reducing the resistivity of petroleum coke and making the porosity better. Moreover, after 12 processes, the micro-pores in each carbon particle are treated, so that the indexes of “super pass, quick melt and absorption rate” in the process of use are greatly improved.

The raw material of high-quality calcined coke is petroleum coke, but it is very easy to distinguish them. From the surface, the metal luster of calcined coke is stronger, and the carbon pores are more transparent after calcined. The density of petroleum coke is a little higher and heavier than that of calcined coke. The main component of petroleum coke is carbon, and the rest is water, ash, sulfur and other impurities, and the calcined coke after the calcined petroleum coke to remove a large number of water ash and other mineral impurities, that is to say, the more sufficient the calcined raw materials, the better the component index of calcined coke, the more favorable to the quality of the product.

To sum up, the raw material of high quality calcined coke is petroleum coke, and the controlled temperature calcination process of Jia-carbon nine-layer countercurrent tank calcination furnace can ensure the calcined quality of petroleum coke and produce high quality calcined coke after 48 hours of controlled temperature calcination.
