Abstract
ABSTRACTThe paper deals with comprehensive quality and physical parameters of commercial cokes. It aims to present comparative analysis of acquired values with standards found in other literature sources. There were analysed 15 samples of coke from current industrial operation. There were carried out chemical analysis, CSR and CRI characterization. Density, porosity, compressive strength, friction coefficient, volume of particles were determined. There was performed one-way analysis of variance (ANOVA) by Statistica v.12.0 (StatSoft, Inc., Tulsa, USA) to determine significant correlation between the measured parameters. The highest correlation coefficents were noted between the pycnometer density of cokes and CSR index (r = 0.925) and CRI index (r = −0.828). The comparative analysis of quality and physical parameters with values mentioned in literature revealed the significant differences in the values of apparent density, bulk density and true density of pulverized samples.
