Petroleum coke has a high carbon content, typically ranging from 85% to 95%. This makes it an excellent source of carbon for industries that require carbon-rich materials such as steelmaking, Aluminum smelting, and the production of carbon and graphite-based products. Petroleum coke has a high calorific value, meaning it releases a significant amount of heat energy when burned. This makes it an efficient fuel source for power generation, Cement kilns, and other industrial processes that require high heat. Calcined petroleum coke, in particular, has excellent electrical conductivity due to its carbon content. This makes it an ideal material for the production of carbon and graphite electrodes used in industries like aluminum smelting and steelmaking, where electrical conductivity is crucial.

Petroleum coke is commonly used as a fuel source in power plants, cement kilns, and other industrial facilities. Its high carbon content and calorific value make it an efficient fuel for generating heat and energy. Calcined Petroleum coke is a critical component in the production of carbon anodes used in the aluminum smelting process. Anodes are consumed during the electrolytic process of producing aluminum, and petroleum coke provides the necessary carbon and electrical conductivity required for efficient aluminum production.

Petroleum coke is a valuable source of carbon and is used in the production of carbon electrodes, graphite electrodes, and other carbon-based products. These products find applications in industries such as steelmaking, aluminum smelting, and the production of batteries, fuel cells, and various electronic components. Petroleum coke is sometimes used in the production of refractory materials, which are heat-resistant linings used in furnaces, kilns, and reactors. The high carbon content of coke can provide thermal stability and resistance to high temperatures in these applications.

Petroleum coke has various non-combustible applications such as graphite electrodes, carbon electrodes or anodes in various industries such as aluminum and steel. At first it was tought only as a fuel like coal. Today, it is sold in two types, raw (green) and calcined, which is used as fuel because the amount of sulfur and ash is high and no other use can be imagined for it. This coke is used in cement industry, water and electricity units, refineries and paper industries. 

Because this fuel alone does not have enough volatiles to create a flame, 70% Coal and 30% coke are used. In the cement industry, due to the presence of abundant sulfur in the coke, there is no need to add separate sulfur to the cement, which is a good fuel. Medium quality petroleum coke is also used as a carbon source in various alloy industries, which is considered as an additive. It is also used in the form of calcination, which is used in the industries of aluminum, arc melting furnace electrodes, graphite electrodes, and the production of titanium dioxide pigment. 

The important and strategic point in this part is that the presence of sulfur causes rapid electrode corrosion and swelling, which causes rapid electrode breakage. Also, the presence of Metals such as nickel and vanadium in coke causes rapid oxidation of the anode in industry. Petroleum coke is used as a source of carbon in the production of steel. It is added to the iron ore and other materials in blast furnaces to act as a fuel and provide the necessary carbon content for the steelmaking process. Petroleum coke is used in various industrial processes that require high heat and energy. It can be used as a fuel in boilers, furnaces, and kilns for applications such as cement manufacturing, Lime production, and Chemical processes.

Petroleum coke is a byproduct of the petroleum refining process, which means it is readily available in large quantities. Refineries produce petroleum coke as part of their operations, and this abundance makes it an economical choice for various industries. Petroleum coke can be processed and modified to meet the specific requirements of different industries. Through calcination, volatile matter and moisture can be removed, resulting in higher-quality calcined coke suitable for anode production and other specialized applications. Additionally, petroleum coke can be blended with other fuels or materials to optimize its properties for specific uses. Petroleum coke is often a cost-effective alternative to other fuels and carbon sources. Its availability and relatively low cost compared to alternative materials make it an attractive choice for industries seeking economical solutions.
