The Influence of GPC Calcination Technology and Crystallite Size (Lc) of CPC on the Quality and Performance of Carbon Anodes
摘要
The results indicate that a higher calcination temperatureCalcination temperature of petroleum cokePetroleum coke and a finer grind of calcined coke lead to a higher coke yield of coal tar pitchCoal tar pitch during the bakingBaking of green anodesAnode. The calcined coke finesFines and coal tar pitchCoal tar pitch are kneaded to form a new phase—the binder phaseBinder phase. Within this binder phaseBinder phase, the pitch is chemically bonded to the surface of the fineFines coke particles. A higher calcination temperatureCalcination temperature and a finer grind of the calcined coke promote the formation of a greater quantity and higher qualityQuality of this binder phaseBinder phase, which consequently influences the physical and chemical propertiesProperties of both the green anodesAnode and the baked anodesAnode. A higher calcination temperatureCalcination temperature results in a larger LcLc value of calcined coke. When using the calcined cokes with LcLc between 3.4–3.6 nm, high-qualityQuality carbon anodesCarbon anode are produced.
