Features and properties of petroleum coke
Petroleum coke (calcified petroleum coke) has several characteristics and properties, some of which we will examine below:
1. Graphite structure: petroleum coke has a graphite structure, which means having graphite layers made up of carbon atoms. This structure can give petroleum coke high strength and significant mechanical strength.
2. High carbon content: coke usually has a high carbon content that can make up to 90% or more of its weight. This feature makes petroleum coke a rich source of carbon.
3. Heat resistance: cokeDue to its graphite structure and high carbon content, it has very high heat resistance. This property makes it suitable for use in industrial processes that require high heat, such as aluminum and steelmaking processes.
4. Reducing the amount of polluting gases: Petroleum is used as fuel in combustion processes. With the combustion of coke, the amount of polluting gases such as greenhouse gases, carbon dioxide gases and other pollutants is significantly reduced.
5. Chemical stability: petroleum coke has high chemical stability. This means its resistance to chemical changes and decomposition. This feature allows coke to be used in long-term industrial processes and to act as a stable material in harsh conditions and environments with high temperature and pressure.
6. Consumption in the steel industry: petroleum is used as one of the main materials in steel production. Due to its high carbon content and thermal properties, this material is used in steel production processes such as electric arc and arc furnaces.
7. Use in the production of graphite electrodes: coke is used as one of the main materials in the production of graphite electrodes. These electrodes are used in industries such as steel making, aluminum making, and chemical industries, and they have requirements such as heat resistance, good electrical conductivity, and chemical stability, which petroleum coke meets these requirements well.
In general, because of its characteristics and properties, coke has wide applications in various industries including steel industry, aluminum industry, graphite electrode industry and energy production.
