graphitized petroleum coke-Petroleum Coke Testing Laboratory
Petroleum Coke, or petcoke as it is sometimes commonly referred to, is a byproduct created in the refining process of heavy crude oil. During the distillation of the crude into the many various fractions and products (gasoline, diesel, fuel oil, jet fuel, kerosene, naphtha, lubricants, waxes, etc.), components of the crude known as bitumens which contain a higher number of carbon atoms than regular oil are left over as the final by-product residue. This residue is further processed by modern refineries in thermal cokers to extract additional gas and oil products with the final product being a carbon-rich solid material that we refer to as a coke.
