Characterization of petroleum coke as an additive in metallurgical cokemaking. Influence on metallurgical coke quality

摘要

The relavance of petroleum coke activity during the plastic stage in cocarbonization with a low-volatile bituminous coal was assessed b establishing differences in lowering of Gieseler maximum fluidity of the blend (bituminous coal and petroleum coke) and in metallurgical coke quality. Differences in fluidity of the blend were well correlated with parameters used in petroleum coke characterization such as hydrogen donor ability, the volatile matter released between 400 and 500 deg.C, and the ratio of methyl and methylene groups in aromatic clusters.
