Comparative study on calcination of weight loss for coking and calcined coke properties used for aluminum anode –grade

The aim of the present paper consists in the evaluation of the physical-chemical characteristics of some petroleum coke, before and after thermal treatment, which was used to observe the alterations which took place over the coke’s quality. The impact of heat treatment (temperature, heat-soak time and heating rate) on petroleum coke properties were examined. Investigated coke produced from feedstock with different compositions. the sulphur content, volatile matter, density value and ash content before and after heat treatment to 1100 °C were analysed. These properties along with low metals and ash contents make calcined petroleum coke the best material currently available for making carbon anodes
