Carbon black production from various sources by thermal cracking method

Abstract

Petroleum-based feedstock (PBFS) and Coal tar-based feedstock (CTBFS) were used for the synthesis of carbon black (CB) via thermal cracking method named as Petroleum-based feedstock carbon black (PBFS-CB) and Coal tar-based feedstock carbon black (CTBFS-CB) in a furnace reactor at a temperature of 1800 °C, for utilizing industrial waste products. The obtained distinguish carbon black samples are characterized for determining functional groups, morphology, and surface area using advanced instruments. Further, investigated physical and mechanical properties of obtained different CB samples mixed into the natural rubber. The small clusters morphology is observed in CBs. There are slight changes in spectra peaks and there no significant new peaks are observed. The same minerals observed at same theta values in XRD pattern corresponding to PBFS-CB and CTBFS-CB. The tensile strength, modulus 300% and abrasion loss of samples into rubber were determined as per international ASTM standards. The results revealed that, there are negotiable values observed in both samples due to minimal changes observed in surface area of the CB samples. These samples can be used for various applications viz rubber reinforcement, conductivity agent, colouring agent, and ultraviolet screening agent etc.
