Production process
Raw material selection: Low sulfur petroleum coke (sulfur content<1.5%) is preferred, as excessive sulfur content can affect the quality of downstream products (such as the purity of electrolytic aluminum).
Calcination process:
In a vertical calcination furnace or rotary kiln, petroleum coke is heated to 1200-1500 ℃ under isolated air conditions.

Calcination process:
In a vertical calcination furnace or rotary kiln, petroleum coke is heated to 1200-1500 ℃ under isolated air conditions.
Key reactions:
The volatile components (H2, CH4etc.) further precipitate, and the content decreases from 8% -15% of the coke to below 1%.
The carbon structure is rearranged to form tighter graphitized microcrystals, improving electrical and thermal conductivity.
Cooling and crushing: The calcined coke is cooled by water or air cooling and crushed to the desired particle size (such as 0-10mm, 10-20mm).
Calcined Petroleum coke is a carbon material formed by high-temperature calcination (1200-1500 ℃) of petroleum coke (a byproduct of oil refining) to remove volatile matter and moisture. Its essence is to convert low-purity raw coke into structurally stable and performance-optimized calcined coke through physical and chemical reactions, which is widely used in high-end fields such as electrolytic aluminum, graphite electrodes, and lithium batteries.
