Abstract Scope |
Worldwide, the quality of petroleum coke, used for making carbon anode for aluminium smelters, is getting degraded with increase in impurities and higher presence of shot coke particles. Earlier studies reported that some of the anode problems like slabbing and vertical cracking are linked to thermal shock resistant of coke material, which is majorly influenced by the structure of calcined petroleum coke (CPC). Therefore, a detailed method of optical microscopic analysis established and successfully applied to evaluate CPC materials. The analysis of most of the samples, were found to have presence of mixed and isotropic structure. The findings of the optical microscopy have been corelated with the visual identification of shot, sponge & needle coke. The visual identification of different coke particles enables its integration with digital image processing techniques for ease of quantification of specific coke material. |
