Effect of cobalt chloride on the physical and chemical properties of the solid residue from the pyrolysis of polymer tire cord

This work is focused on the effect of cobalt chloride on the physical and chemical properties of the pyrolysis residue of the polymer cord from scrap tires. It has been demonstrated by X-ray fluorescence analysis that the greater part (∼90%) of the catalyst used in polymer cord pyrolysis remains in the solid carbon residue, thus making possible catalyst regeneration. Use of cobalt chloride increases the specific surface area of the solid residue by 15% and reduces its zinc content by 70%. This is favorable for achieving a better quality of potential sorbents based on the polymer cord pyrolysis residue.
