Calcined Petroleum Coke
BZNCarbon’s Calcined Petroleum Coke (CPC) is a premium-grade, high-carbon material obtained through the controlled thermal processing of Green Petroleum Coke (Raw Petroleum Coke – RPC). This transformation occurs in rotary kilns at temperatures between 1200°C and 1400°C, during which moisture, volatile matter, and impurities are eliminated—resulting in a highly pure, electrically conductive, and chemically stable carbon material.
Description
What is CPC and How is It Made?
CPC is produced by calcining green petroleum coke, a by-product of crude oil refining. After mechanical crushing and sizing, the RPC is introduced into a calcination furnace. The process enhances its density, purity, and conductivity, making it a valuable raw material for industries that require high-performance carbon additives or structural materials under high-temperature conditions.
Key Applications
BZNCarbon’s GRADE-A CPC is ideal for applications where low ash and sulfur levels are crucial to performance and product quality. It is widely used in:
Aluminum Industry: As an anode material in aluminum smelting via Hall-Héroult process.
Steel & Ferroalloy Production: Acts as a carbon additive and recarburizer in electric arc furnaces.
Titanium Dioxide Production: Used as a reducing agent during the chloride process.
Foundry Applications: Serves as an inoculant or carburizer for cast iron and ductile iron casting.
Graphite Electrode Manufacturing: Used in the production of synthetic graphite rods and blocks.
Its high thermal resistance, electrical conductivity, and structural integrity make it ideal for high-temperature processes in aggressive chemical or metallurgical environments.
