Graphitized Petroleum Coke (GPC) Overview
Graphitized Petroleum Coke (GPC) is a high-quality carbon additive produced from petroleum coke through a high-temperature graphitization process. This process transforms the carbon structure into a more stable graphite form, resulting in high fixed carbon content, low sulfur content, low ash, and excellent carbon absorption performance.
GPC is widely used as a premium recarburizer in steelmaking, iron casting, ductile iron production, and other metallurgical processes where precise carbon adjustment and low impurity levels are required.
Compared with ordinary petroleum coke, Graphitized Petroleum Coke provides higher carbon efficiency, faster dissolution, and better metallurgical performance, making it a preferred carbon additive for modern steel mills and foundries.
Why Choose GPC as a Recarburizer?
In steelmaking and foundry production, carbon content directly affects the mechanical properties and quality of final products. An efficient recarburizer helps manufacturers accurately control carbon levels while minimizing unwanted impurities.
Graphitized Petroleum Coke offers:
  • High Fixed Carbon Content - Improves carbon recovery efficiency during melting
  • Low Sulfur and Low Nitrogen Options - Suitable for applications requiring strict impurity control
  • Excellent Carbon Dissolution Rate - The graphitized structure allows faster carbon absorption into molten iron and steel
  • Stable Chemical Composition - Helps maintain consistent production quality between different batches
  • Reduced Slag Formation - Low ash content contributes to cleaner metallurgical processes
GPC Chemical Specifications
Item Typical Specification
Fixed Carbon (FC) 98.5% min / 99% min
Sulfur (S) ≤0.05% / ≤0.03%
Ash ≤0.5%
Moisture ≤0.5%
Volatile Matter ≤0.5%
Nitrogen (N) According to customer requirements
Size 0-1mm, 1-5mm, 5-10mm, or customized
Specifications can be adjusted according to steel mill and foundry requirements.
Production Process of Graphitized Petroleum Coke
1. Selection of High-Quality Petroleum Coke
Low sulfur petroleum coke is selected as the raw material to ensure stable carbon content and impurity control.
2. High-Temperature Graphitization
The petroleum coke is treated under extremely high temperatures in a graphitization furnace. This process improves carbon crystallinity, electrical conductivity, carbon absorption efficiency, and metallurgical performance.
3. Crushing and Screening
After graphitization, the material is crushed and screened into different particle sizes according to customer requirements.
4. Quality Inspection
Each batch is tested for fixed carbon, sulfur, ash, moisture, and particle size distribution.
Applications of GPC Recarburizer
Steelmaking Carbon Additive
Graphitized Petroleum Coke is used in electric arc furnace (EAF) and induction furnace steelmaking to increase carbon content and adjust molten steel chemistry.
Typical applications:
  • Carbon steel production
  • Alloy steel production
  • Special steel manufacturing
Benefits:
  • Improve carbon recovery
  • Reduce sulfur introduction
  • Support stable steel quality
Foundry and Cast Iron Production
GPC is widely used as a recarburizer for gray cast iron, ductile iron, and cast steel. It helps foundries control carbon equivalent, graphite structure, and mechanical properties.
Metallurgical Carbon Additive
Other applications include ferroalloy production, synthetic graphite production, and metallurgical additive processes.

FAQ About Graphitized Petroleum Coke (GPC)
1. What is Graphitized Petroleum Coke (GPC)?
Graphitized Petroleum Coke is a carbon additive produced by graphitizing petroleum coke at high temperatures. It is mainly used as a recarburizer in steelmaking and foundry applications.
2. What is GPC used for?
GPC is mainly used for increasing carbon content in molten steel and iron, especially in electric furnace steelmaking, cast iron production, and ductile iron manufacturing.
3. What is the difference between GPC and CPC?
GPC has undergone graphitization treatment, giving it a more ordered carbon structure, higher carbon absorption efficiency, and better performance compared with calcined petroleum coke (CPC).
4. What GPC carbon content is available?
Common grades include:
  • FC 98.5% min
  • FC 99% min
Higher carbon grades can be supplied according to application requirements.
5. What sulfur content can GPC achieve?
Low sulfur GPC grades are commonly available with sulfur levels such as:
  • ≤0.05%
  • ≤0.03%
Specific sulfur requirements can be customized.
6. How should I select GPC particle size?
Particle size selection depends on furnace type and addition method. Fine sizes are often used for faster dissolution, while larger particles may be suitable for certain furnace charging processes.
