Calcined Petroleum Coke
Product Details:
Calcined petroleum coke (CPC) is a critical ingredient in aluminum smelting and other metallurgical processes. It’s produced by calcining raw petroleum coke, a by-product of oil refining, to remove moisture and volatile organic compounds. This process increases its purity and crystalline structure, enhancing its electrical conductivity and physical properties.
Here’s a table detailing the typical characteristics and specifications of calcined petroleum coke:
| Property/Specification | Description | Typical Values |
|---|---|---|
| Fixed Carbon Content | The amount of carbon present after impurities are removed. | 99%. |
| Sulfur Content | Amount of sulfur, which can impact the quality of the final product. | 1%. |
| Ash Content | The residue left after combustion, indicating purity. | 0.5%. |
| Volatile Matter | Compounds that vaporize at high temperatures. | 0.5%. |
| Moisture Content | Amount of moisture, which can affect handling and quality. | Low, typically <0.5%. |
| Bulk Density | Mass per unit volume, impacting handling and storage. | Ranges from 0.65 to 0.80 g/cm³. |
| Real Density | Density of the solid material excluding pore space. | Approximately 2.05 – 2.10 g/cm³. |
| Particle Size | Size of the granules, affecting reactivity and blending. | Customizable as per requirement. |
| Electrical Resistivity | Resistance to electrical current flow. | Low, suitable for anode production. |
| Thermal Conductivity | Ability to conduct heat. | Moderate to high. |
Applications:
- Aluminum Smelting: As a carbon anode, essential in the Hall-Héroult process.
- Steel Making: In the production of graphite electrodes.
- Titanium Dioxide Production: As a reducing agent.
- Chemical Industries: In the manufacture of synthetic graphite and other carbon products.
- Friction Industries
Handling and Safety:
- Storage: Should be kept dry to prevent moisture absorption.
- Safety: Dust masks and protective gear recommended to avoid inhalation and skin contact.
