Development of conductive carbon black from discarded tires

Abstract:
The carbon black material used as reinforcing filler in tires was recovered by pyrolysis at a temperature of 490¢XC and at atmospheric pressure. The pyrolytic carbon black obtained (CBp) was contamined by various additives of the original tire. Contaminants were also produced by chemical reactions occurring in the pyrolysis reactor. The recovered carbon black was performed and a possible reduction of the ash content by hydrochloric acid treatment.
After the demineralization treatment, the recovered pyrolytic carbon black (CBP) was heated in a post-pyrolysis process at temperatures ranging from 670 to 1170 ¢XC. The CBP were studied by low-pressure nitrogen adsorption and surface spectroscopic method ( SIMS), Raman spectroscopy, XRD, TPD, TEM. Furthermore, the CBP properties were correlated to their electrical conductivities.
