Medium Sulfur Calcined Petroleum Coke
Medium sulfur calcined petroleum coke is a cost-efficient calcined carbon material processed from medium-sulfur green coke via high-temperature rotary kiln calcination. Its sulfur content ranges from 1.5% to 3.0%, with stable fixed carbon and good electrical conductivity. This grade is the mainstream raw material for aluminum prebaked anodes, industrial silicon smelting and silicon carbide production, balancing stable performance and competitive cost for mass industrial production. We supply consistent batch medium sulfur CPC with customizable particle sizes for global aluminum, metallurgy and chemical manufacturers.

Production Process Highlights
Continuous high-temperature calcination—Raw coke is heated at 1200–1300℃ to remove moisture and volatile components, forming a firm carbon crystal structure.
Crushing and multi-layer sieving—Process calcined coke into various particle sizes to match different furnace and production demands.
Full batch lab inspection—Each shipment undergoes sulfur, ash, and density testing to keep batch indicators consistent.
Standard bulk export packaging- moisture-proof woven bags or bulk container loading to avoid quality loss during long-distance transport.
Core Application Fields
Product Advantages
Stable medium-sulfur index control
Tight raw material and kiln temperature control reduces sulfur fluctuation across batches.
High cost performance
More economical than low-sulfur CPC while meeting the standard requirements of aluminum and silicon industries.
Flexible particle customization
We adjust granularity from fine powder to coarse particles to fit different production processes.
Large stock & stable bulk supply
Sufficient production capacity supports long-term large-volume orders with complete COA test reports for every batch.
service related FAQ’s
We provide customized packaging, labeling and bulk loading solutions according to customer export requirements.
Yes, every shipment comes with complete COA quality certificates and test data for customs and factory inspection.
All batches are strictly tested with fixed industrial standards, ensuring stable and consistent quality for long-term bulk supply.
We provide low-sulfur and medium-sulfur green petroleum coke, as well as low-sulfur and medium-sulfur calcined petroleum coke for diverse industrial needs.
Green petroleum coke is raw uncalcined coke with higher volatile content, while calcined coke is high-temperature processed for stable carbon structure, low volatility and better conductivity.
