Calcined Petroleum Coke for Titanium Dioxide Production: A Key Raw Material for the Chloride Process

Calcined Petroleum Coke for Titanium Dioxide Production | Reliable CPC Supplier for the Chloride Process

Titanium dioxide (TiO₂) ranks among the most widely used white pigments in the world. Manufacturers rely on it in coatings, plastics, inks, paper, and many other industrial products. Modern titanium dioxide plants often use the chloride process, which requires a stable carbon source during chlorination.
Calcined petroleum coke (CPC) plays a crucial role in this stage. Titanium dioxide producers depend on high-quality CPC to ensure stable chemical reactions and efficient TiCl₄ generation.

As an experienced calcined petroleum coke supplier, ShanChun Carbon® provide reliable CPC materials that support titanium dioxide plants worldwide.

The Role of Calcined Petroleum Coke in the Chloride Process

Titanium dioxide producers convert titanium ore into titanium tetrachloride through chlorination. This stage requires chlorine gas and a carbon source.

Calcined petroleum coke supplies the carbon required for the reaction. The carbon removes oxygen from titanium oxide and enables the formation of titanium tetrachloride.
The simplified reaction follows this path:
TiO₂ + 2Cl₂ + C → TiCl₄ + CO₂

Titanium tetrachloride then undergoes purification and oxidation to form high-purity titanium dioxide pigment. Because this reaction operates at high temperatures, titanium dioxide plants require carbon materials with stable chemical and physical properties. Calcined petroleum coke provides the consistency required for this process.

Why Titanium Dioxide Plants Use Calcined Petroleum Coke Instead of Raw Coke

Raw petroleum coke contains volatile matter and unstable structures. These characteristics reduce process stability during chlorination.
Calcination transforms petroleum coke at temperatures above 1200°C. This process removes volatile components and improves carbon purity.
As a result, calcined petroleum coke offers several advantages for TiO₂ production.
High Fixed Carbon Content
Calcination increases fixed carbon levels and improves reaction efficiency. High carbon purity supports stable chlorination.
Low Volatile Matter
Low volatile content reduces unwanted reactions in the reactor and improves process control.
Strong Structural Stability
Calcined petroleum coke maintains structural integrity under high-temperature industrial conditions.
Consistent Chemical Performance
Stable chemical composition allows titanium dioxide plants to maintain predictable reaction behavior.
These advantages explain why most chloride-process TiO₂ plants specify calcined petroleum cokeas the preferred carbon source.

Key Quality Parameters for Titanium Dioxide Producers

Titanium dioxide manufacturers evaluate calcined petroleum coke according to several technical indicators. Stable quality across these parameters ensures reliable operation.
Key specifications usually include:

• Fixed Carbon Content
• Sulfur Content
• Ash Content
• Volatile Matter
• Particle Size Distribution
• Real Density
  Each TiO₂ plant may define its own particle size range depending on reactor design and feeding systems.
