Product Description
Product Overview
Xingshi calcined petroleum coke (CPC) with 98.5% fixed carbon ensures high conductivity and low impurity for aluminum smelting anodes, reducing production cost!
Low Sulfur CPC (98.5%)-
Production process
Raw material selection: Low sulfur petroleum coke (sulfur content<1.5%) is preferred, as excessive sulfur content can affect the quality of downstream products (such as the purity of electrolytic aluminum).
Calcination process:
In a vertical calcination furnace or rotary kiln, petroleum coke is heated to 1200-1500 ℃ under isolated air conditions.
Key reactions:
The volatile components (H2, CH4etc.) further precipitate, and the content decreases from 8% -15% of the coke to below 1%.
The carbon structure is rearranged to form tighter graphitized microcrystals, improving electrical and thermal conductivity.
Cooling and crushing: The calcined coke is cooled by water or air cooling and crushed to the desired particle size (such as 0-10mm, 10-20mm).

Calcined Petroleum coke is a carbon material formed by high-temperature calcination (1200-1500 ℃) of petroleum coke (a byproduct of oil refining) to remove volatile matter and moisture. Its essence is to convert low purity raw coke into structurally stable and performance optimized calcined coke through physical and chemical reactions, which is widely used in high-end fields such as electrolytic aluminum, graphite electrodes, and lithium batteries.

Features & Advantages
Calcined Petroleum Coke (CPC) – Features & Advantage
1. Key Features
≡High Fixed Carbon (98–99.5%)– Ensures superior conductivity and carbon yield in industrial processes.
≡Low Sulfur (0.3–0.8%) – Minimizes pollution and improves metal quality in aluminum/steel production.
≡Low Ash (0.5–1.2%) - Reduces impurities in end products (e.g., anode blocks, refractories).
≡Controlled Particle Size (0.5–25mm) – Customizable for optimal performance in carburizing or anode paste.
≡High Thermal Stability – Withstands temperatures up to 1,500°C without degradation.
2. Competitive Advantages
Cost-Effective
· Replaces premium carbon additives (e.g., graphite) at 30–50% lower cost while maintaining performance.
Process Efficiency
· Faster Carburization: Uniform particle size ensures rapid dissolution in molten metal (steel/iron).
· Reduced Energy Use: Low volatile matter (≤0.5%) cuts furnace energy consumption.
Custom Solutions
· Tailored blends for specific needs (e.g., ultra-low sulfur for Li-ion battery anodes).
Reliable Supply
· Vertical integration from raw coke to calcined product ensures stable quality and volume.
· Strategic stock for fast delivery.
