Graphitized Petroleum Coke

详情

Graphitized Petroleum Coke (GPC) is a high-quality carbonaceous material derived from high-temperature treatment of petroleum coke. The process of graphitization involves heating raw petroleum coke to elevated temperatures (typically above 2500 degrees Celsius). This results in the rearrangement of the carbon atoms, converting the amorphous carbon structure of petroleum coke into a crystalline graphite structure.

Key properties of graphitized petroleum coke include:

1. High Carbon Content: GPC typically has a very high carbon content, exceeding 99%. This makes it a valuable material in industries where high purity and carbon content are essential.

2. Low Impurities: The graphitization process removes most of the impurities present in the raw petroleum coke, resulting in a material with low sulfur, nitrogen, and other volatile content.

3. Excellent Thermal Conductivity: Graphitized coke has high thermal conductivity, making it suitable for applications where efficient heat transfer is crucial & electrical conductivity is essential.

4. Good Lubricating Properties: The lubricating properties of graphite are utilized in certain applications, and GPC can be employed in the production of graphite lubricants.

The primary applications of graphitized petroleum coke include:

1. Manufacturing of Graphite Electrodes: GPC is a crucial raw material in the production of graphite electrodes used in electric arc furnaces for steel production. Graphite electrodes conduct electric current and provide the necessary heat for the melting process.

2. Production of Carbon Raisers: GPC is used as a carbon additive in the production of carbon raisers, which are added to molten metal during steelmaking to adjust carbon content.

3. Other Industrial Applications: GPC may find use in other industrial applications requiring high-purity carbon with excellent thermal and electrical conductivity.

Graphitized petroleum coke is a valuable material in industries that require high-performance carbonaceous materials.
