Özet

In order to reduce the cost and also enlarge the solid carbon source suitable for the formed coke production further investigations were conducted to produce formed coke using anthracite which can provide a new and relatively economic abundant raw material suitable for this purpose. The results indicated that, anthracite can also be used for the production of metallurgical quality formed coke, but the tensile strength of the anthracite formed coke were found to be comparatively lower than that of the coke breeze formed coke, 64.6 MPa, 73.2 MPa, respectively, when carbonized at 950 degrees C for 1 h, due to the decomposition of the volatiles that causes fissures, cracks and new pores. To produce anthracite briquettes of higher tensile strength, either anthracite of lower volatile matter should be used or it should be blended with coke breeze. (C) 2010 Elsevier B.V.
