Petroleum coke calcine or CPC is a hard and penetrable carbon material obtained from various sources such as petroleum tar, coke fines, and coal. Due to its properties such as high heat and chemical resistance, corrosion resistance, and high hardness, it is widely used as an important raw material in the aluminum industry.
One of the main applications of petroleum coke calcine in the aluminum industry is its use as a reducing agent in the electrolysis process for producing aluminum. In this process, petroleum coke calcine is used as a reducing agent in the cathode, which reduces the aluminum oxide present in the alumina melt, resulting in metallic aluminum being obtained in the cathode. Additionally, petroleum coke calcine is used as one of the main materials in the production of carbon electrodes for the electrolysis process.
Furthermore, due to its positive properties towards heat and chemical resistance, petroleum coke calcine is also used in other industries. For example, in the steel industry, it is used as a reducing agent for producing sponge iron and steel. Additionally, in the chemical and paint industries, petroleum coke calcine is used as one of the main materials in the production of catalysts and paints.
