Calcined Petroleum Coke (CPC) | Reliable Calcined Coke Supplier from China

Calcined Petroleum Coke

Calcined Petroleum Coke (CPC) is produced by high-temperature treatment of green petroleum coke to remove volatiles and impurities. It has high fixed carbon, low resistivity and stable carbon structure, widely used as core carbon raw material for aluminum, metallurgy, new energy and refractory industries. We supply low-sulfur and medium-sulfur calcined coke with stable batch indexes, supporting customized specifications and large export orders for global manufacturers.

Standard Technical Parameter Range

Raw Coke Sorting & Preprocessing—We screen raw green coke, remove impurities, and classify materials by sulfur and ash content for targeted calcination.

Rotary Kiln High-Temperature Calcination—Raw coke is heated at 1200–1400℃ in rotary kilns to fully remove moisture and volatiles, improving density and electrical conductivity.


Cooling, Crushing & Sieving—Calcined coke is cooled, crushed, and screened to form uniform particle sizes per customer demand.


Batch Inspection & Finished Packing—Every batch is tested for key indicators; qualified products are packed and stored in dry warehouses to avoid dampness before delivery.
