Calcined Petroleum Coke CPC - 1-3mm, 1-5mm, 0.2-1mm,
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!
Production 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.
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 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).

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
