Ferric chloride and benzene were examined with many other chemicals to be used as solvents for the sulfur‐bearing compounds present in the Egyptian petroleum coke. The best results were obtained when ferric chloride and benzene were used consecutively, and more than 35% degree of desulfurization was obtained in this case. The kinetic study showed that the combination of the three rate processes, namely for diffusion of ferric chloric through a liquid film, surrounding the coke particles, and in the coke ash layer, plus chemical reaction of the ferric chloride with the sulfur‐bearing compounds present in the petroleum coke, will provide overall control of the process. Activation energy of the process was found to be 12 kJ/mol.
