Low Sulphur Low Nitrogen Semi Graphitized Petroleum Coke

Low sulfur low nitrogen semi graphitized petroleum coke is a high-end, refined carbon material. Produced from premium raw petroleum coke, it undergoes multiple processing steps, including calcination, graphitization, deep impurity removal, crushing, and precision screening. Characterized by high fixed-carbon content and ultra-low ash levels-along with strictly controlled sulfur and nitrogen content-it differs from both standard calcined petroleum coke and fully graphitized petroleum coke. Its carbon atoms form a semi-ordered graphitic crystal structure, offering a balance of excellent dissolution/permeability, electrical and thermal conductivity, and cost-effectiveness. It serves as a key auxiliary material for high-end metallurgy, precision casting, and carbon product manufacturing.

This product overcomes the common drawbacks of standard petroleum coke-such as excessive sulfur and nitrogen, low absorption rates, and melt contamination-while avoiding the high costs associated with fully graphitized petroleum coke. With stable physicochemical properties and strong batch-to-batch consistency, it meets the rigorous production standards of sectors including high-end specialty steel, ductile iron, aluminum electrolysis, and carbon electrode manufacturing, making it a highly cost-effective choice among industrial carbon materials.

Product Advantages

• 1. Ultra-low impurities, rigorous quality standards

Processed via high-temperature, deep impurity removal, the product features sulfur and nitrogen levels far below those of standard petroleum coke. This effectively prevents quality defects-such as porosity, cracking, and embrittlement-caused by sulfur and nitrogen impurities during smelting and casting, ensuring no degradation in the performance of steel or castings and meeting the demands of high-end production.

• 2. High absorption rate, minimal loss

The semi-graphitized crystal structure features moderate porosity and uniform pore distribution, maximizing contact area with the molten metal. This ensures rapid dissolution and uniform permeability, achieving a carbon absorption rate exceeding 92%-far higher than that of standard calcined petroleum coke-thereby reducing raw material waste and lowering production costs.

• 3. Stable performance, consistent batches

Produced using fully intelligent temperature control, the material boasts a stable carbon atomic structure, high fixed-carbon content, and ultra-low volatile matter. There is no violent volatilization or abnormal combustion during processing, allowing for precise control of melt composition. Minimal deviation in physicochemical indicators across batches ensures the stability of the customer's production process.

• 4. Excellent Cost-Performance Ratio and Broad Compatibility

Its performance rivals that of high-end fully graphitized petroleum coke, allowing it to substitute for more expensive fully graphitized products while offering a price advantage. It balances high performance with low cost and comes in a full range of particle sizes, meeting the production needs of various industries and equipment types.

Application Areas

1. Iron and Steel Smelting Industry

Widely used as a premium recarburizer in the smelting of specialty steel, alloy steel, and carbon steel. It enables precise control of carbon content in molten steel, enhancing strength, toughness, and wear resistance. Its low-sulfur and low-nitrogen characteristics effectively ensure the purity and mechanical properties required for high-end steel products.

2. Foundry Industry

Suitable for the production of ductile iron, gray iron, and precision castings. It effectively improves the fluidity of molten iron and refines grain structure, preventing defects such as porosity, looseness, and cracking. By increasing casting density and the pass rate of finished products, it serves as a core recarburizing additive for high-end precision casting.

3. Aluminum Electrolysis and Chemical Industries

Used as a raw material for graphite cathodes in aluminum electrolysis cells; its high-temperature resistance, corrosion resistance, and extremely low impurity levels help extend cathode service life. It also functions as an industrial reducing agent and an adsorbent for heavy metals in wastewater, making it suitable for fine chemical production processes.

4. Other High-End Industrial Sectors

Applicable in fields such as high-end refractory materials, metallurgical additives, and carbon materials for new energy applications. Its stable physical and chemical properties meet the precise formulation requirements for high-end industrial materials.
