Abstract :

Recently issues faced by cokemakers connected with availability of resources, coal quality and price, and environmental concerns have led to the development of coal pre–treatment. Aiming the use of semi–coking coal, technologies for increasing bulk density have been applied such as iquetting and coal moisture control (CMC) which have proved their benefits on manufacturing of a strong metallurgical coke. This work showed coke with high quality regarding bulk density, CSR, DI and coke % > 25 mm was produced from addition of iquettes 20% in the coal blend. For those cokes produced from CMC, coke containing moisture 4% in coal blend presented better properties than cokes with excessive moisture. It was disclosed the effect of iquettes 20% on coke quality is equivalent to produce coke with moisture 4%.
