Petroleum coke is an oil refinery by-product that is rich in carbon and is used in a number of industrial applications. It is a vital fuel for electric vehicle and alternative energy sources. It is important to use quality assurance measures when producing and processing calcined coke. This will ensure that it meets industry standards and can be used safely.
The production of petcoke begins with crude oil, which is processed in a coker unit to produce gasoline and jet fuels. Byproducts of the process include petroleum coke (also known as green petroleum coke), fuel oil, and a waxy substance named paraffin. The coke - also known as "green petroleum coke" - is a solid material with low volatile matter content and moisture. It can be used to provide industrial heat or power as a replacement for coal, but it must first be processed.
To make calcined petroleum, the green coke must be heated in a rotating kiln. This will remove the volatile matter from the coke and increase its fixed content of carbon. Calcination is the high-temperature treatment that produces a lower-sulfur carbon material. The coke's crystalline structure also makes it a good choice for applications requiring efficient heat transfer.
Calcined petroleum coke is commonly used for aluminum smelting. It can also be used to produce titanium dioxide as a substitute for paints. It can be used to adsorb heavy metals for wastewater treatment and air purification. The high purity makes calcined petrol coke a desirable fuel to generate electricity. Research is currently being done on the use of coke instead of coal in nuclear power plants.
Handling and transporting calcined oil coke is difficult due to its brittleness. Special equipment and care are required to protect the environment and workers. The particle size of the coke can be controlled to suit specific applications, and quality parameters such as bulk density and porosity are monitored to ensure consistency.
Although calcined petroleum is used primarily as a fuel source for power plants, other applications can include graphite brushes and carbon electrodes. It is also being studied as a possible alternative to coal and natural gas for producing energy in the fuel cells.
In addition to its wide range of applications, calcined petroleum coke can be a raw material for several other carbon products, including graphitized petroleum coke (GPC) and carbon black. It can be used in iron and nonferrous smelting and casting processes, as well as forging and forging because of its hardness.
