Petcoke is also known as petroleum coke. This carbon-rich byproduct from crude oil refining has many industrial uses. It is used as a coal alternative in the production of steel, cement, and electricity. It has a low ash content and high heat content which makes it a highly efficient fuel source in these industries. The product can also be calcined and made softer by densifying it. This premium-grade product has a layer structure with a high degree of organization, resulting in excellent wear and friction characteristics. This coke is ideal for the production of graphite electrodes used in electric-arc furnaces within the steel industry.
The primary production unit for coke is the delayed coking system. Under intense pressure and high temperatures, residual oils from other petroleum refinement processes are decomposed into petcoke. It is then treated with hydrogen to remove heavy hydrocarbons and volatiles, resulting in a highly pure carbon material known as calcined oil coke.
CPC has been used as a direct-reduction energy resource in iron-and steel production because it produces less ash. Its lower ash content eliminates or minimizes slag formation during ironmaking and steelmaking compared to coal. This reduces the amount of slag required to be removed from the final product, resulting in less waste and higher product quality.
Due to its high content of carbon, it can be burned at temperatures that are significantly higher than those produced by coal and coke. This increases furnace productivity, and enhances the quality of final steel products. This allows steelmakers a larger variety of products to be produced at a lower price.
Low sulphur levels in petroleum coal allow it to be used in some petrochemical production plants and steelmaking facilities as a fuel alternative. This can be a much safer and cleaner option than the use of other conventional sulphur-based fuels such as bituminous coal and natural gas.
The high carbon content of petroleum coke in the aluminum smelting processes enhances the anode conductivity, allowing for a more reliable product. This helps provide a stable and reliable carbon source to support the growth in plant products for the paper industry.
Graphite petroleum coal is the most common fuel used in arc furnaces to melt magnesium. Its unique characteristics allow it to be used in the production of electrical electrodes of high quality, helping to guarantee high performance and high quality for all applications. Graphite Petroleum Coke is an important raw material used for certain fertilizers. Carbon content of the graphite coke increases the soil nutrient densities and enhances plant growth. It is also used as a raw material in the production of certain fire retardant and waterproofing chemical. It is an ingredient in paints. In addition, a variety of specialty refractory materials are made from petroleum coke.
