Low Sulfur 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.

Production Process Highlights
Precise rotary kiln calcination—Constant temperature control at 1250–1350℃ fully removes volatiles, optimizes carbon crystal structure, and improves conductivity.
Crushing, sieving, and grading—Multiple layers of screening to produce uniform granularity as per customers’ technical drawing requirements.
Multi-index lab testing—Each batch detects sulfur, ash, and density; unqualified products will be reprocessed before delivery.
Sealed export packaging—Moisture-proof bulk bags and container loading to avoid secondary pollution during transportation.
