Scientific novelty
A technology has been developed for producing structured Super Premium grade needle coke from highly aromatized petroleum feedstock modified with a polymer mesogenic additive, for its use in the production of graphite electrodes used in high-power and ultra-high-power electric arc steelmaking furnaces
Advantages
The possibility of obtaining highly structured needle coke with an enhanced microstructure score of 5.8 and a low coefficient of thermal expansion < 1.00 ×10-6 K-1 from petroleum and coal-based industrial raw materials through polymer modification; Beneficial recycling of polymer waste to produce high-margin carbon material
Commercial Implementation
Needle coke is used for the production of large-section graphite electrodes (UHP – Ultra High Power, EGSP – special impregnated graphite electrode, SHP – Super High Power, or EGPK – composite impregnated graphite electrode) used in high and ultra-high power electric arc furnaces. There are currently no alternatives to this type of carbon material. The main consumers of needle coke are electrode manufacturing plants.
