Medium Sulfur Green Petroleum Coke
Medium sulfur green petroleum coke is uncalcined raw coke generated from medium-sulfur residual oil delayed coking. Its sulfur content ranges from 1.5% to 3.0%, featuring stable fixed carbon and moderate volatile matter. It serves as the main raw material for producing medium-sulfur calcined petroleum coke and can be used directly in industrial silicon, silicon carbide, and aluminum anode production. This grade balances stable performance and competitive raw material cost, widely favored by large-scale metallurgical and carbon processing factories. We supply consistent bulk medium sulfur green coke with customizable particle sizes for global industrial buyers.

Production Process Highlights
Raw coke cleaning and sorting—Large coke blocks are washed to remove surface impurities and screened to separate qualified medium sulfur raw materials.
Crushing and multi-layer grading—Raw coke is crushed and sieved into various granularities to match different calcination furnaces and smelting equipment.
Batch sampling quality inspection—Each lot is tested for sulfur, ash, and volatile content to guarantee uniform indicators across shipments.
Bulk storage and export packing—Finished coke is stored in covered yards, packed in moisture-proof jumbo bags or loaded in bulk containers for sea transportation.

service related FAQ’s
Yes, we customize sulfur content, ash content, volatile matter and particle size to match clients’ production processes.
Yes, every shipment comes with complete COA quality certificates and test data for customs and factory inspection.
We provide customized packaging, labeling and bulk loading solutions according to customer export requirements.
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.
With sufficient stock and stable supply channels, we support fast container loading and timely delivery for global clients.
