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.

Applications

Classification and typical applications of Calcined Petroleum Coke- How to Choose Calcined Petroleum Coke?

Aluminum Smelting: Anode blocks, carbon paste.

Steelmaking: Carburizer for EAF/LF furnaces.

Titanium Dioxide: Chlorination process.

Lithium Batteries: Synthetic graphite precursor.

Calcined coke for electrolytic aluminum:

Features: Sulfur content<1.0%, true density>2.08 g/cm ⊃3;, used for producing pre baked anodes (core consumables for electrolytic aluminum).
Application: 90% of the global calcined coke is used in the electrolytic aluminum industry, with a consumption of approximately 500kg of calcined coke per ton of electrolytic aluminum.

Calcined graphite electrode:
Characteristics: Sulfur content<0.5%, volatile matter<0.8%, requiring further processing into needle coke (high-end graphite electrode raw material).
Application: Ultra high power graphite electrodes for electric furnace steelmaking, with a single cost of over 100000 yuan, relying on imported high-end calcined coke.

Calcined coke for lithium batteries:
Emerging field: Improving the energy density of lithium batteries by modifying them as negative electrode material additives
