Methods for modifying needle coke raw materials by introducing additives of various origin (review)

Needle coke, commonly used in the production of high-power graphite electrodes for steel production in electric furnaces, is a scarce product in the refining and by-product coke industry. In recent years, researchers have increasingly turned their attention to various ways of modifying the coal carbonizing process raw materials to produce needle coke and expanding the process raw material base. The review covers a study of different raw materials used to produce anisotropic carbon-based material and summarizes the raw material composition required for needle coke production. Furthermore, additives used to modify needle coke base oil or coal feedstock have been considered and classified according to their mechanism of action.
