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 2 400 °C were analysed.

Results implies partially desulphurization of the coke by performed examinations. Phase analysis of the cokes showed that during the heating, separation and transformation of some inorganic sulphur compounds took place. The sulphides are most stable sulphur compounds identified even after heating coke at 2 400 °C.
