“…This was because DRP was mainly composed of a large amount of rubber and a small amount of carbon black, antioxidant, reinforcing filler, and so on. [ 10, 37, 38 ] It was also found that the content of Zn, Si, and S in M‐g‐DRP was apparently decreased. The results of EDS showed that the surface of DRP was covered with a graft layer of MAH, which was also consistent with SEM.…”

The objective of the article was to enhance the recycling value of solid waste rubber by surface functionalization of desulfurized rubber powder using a one‐pot method based on free‐radical polymerization theory. Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, thermogravimetric analysis, scanning electron microscopy, and elemental analysis were used to characterize the maleic anhydride‐grafted desulfurized rubber powder, and the grafting mechanism was also investigated. Fourier transform infrared spectroscopy and X‐ray photoelectron spectroscopy confirmed that maleic anhydride was grafted onto the desulfurized rubber powder. Thermogravimetric analysis indicated that the maleic anhydride‐grafted desulfurized rubber powder and desulfurized rubber powder possessed different thermal properties and structure. The results of scanning electron microscopy and elemental analysis illustrated that the surface of the desulfurized rubber powder was covered with a layer of fold‐like maleic anhydride polymer. The mechanism of grafting desulfurized rubber powder with maleic anhydride may be achieved by replacing the active α‐H on the methylene group of the desulfurized rubber macromolecule chain.

“…The solid fraction from the ELT pyrolysis process consists of a carbonaceous material composed of the initial carbon black and the inorganic components added during the tire manufacturing processes (mainly Zn and Si) [21,74]. In addition, it may contain other carbonaceous materials since the vapors are transformed into coke through dealkylation or dehydrogenation reactions or are directly adsorbed on the char surface [49].…”

“…The resulting solid fraction is composed of the starting carbon black and the inorganic matter present in the composition of the tires [20]. Among the potential applications of recovered carbon black, its use as a substitute for commercial carbon black stands out [21,22], although some authors study its use as a precursor to obtain activated carbon [23].…”

In this work, chemical recycling as an alternative to conventional end-of-life treatments was studied. Two different types of end-of-life tires (ELT), truck tires and mix tires (50:50 mixture of passenger car and truck tires), were pyrolyzed in a batch microwave reactor. The influence of specific power (10, 20, and 30 W/g) on mass distribution was analyzed. The maximum liquid yield was attained at 10 W/g, while the maximum gas yield is obtained at 30 W/g. Liquid fractions were characterized by gas chromatography/quadrupole mass spectrometry (GC/qMS) to identify the main components, and major compounds were quantified. In all samples, limonene (3.76 ± 0.31–6.80 ± 2.37 wt. %) and BTEX (3.83 ± 0.20–1.19 ± 2.80 wt. %) were the main components. Major limonene concentration is obtained in oil produced from truck ELT while higher yields of aromatic compounds are obtained from mix ELT. The maximum BTEX concentration is obtained at 10 W/g being toluene the main compound with a concentration of 2.07 ± 0.42 and 4.63 ± 1.29 for truck and mix ELT, respectively. The separation and purification of these compounds will confer important value to these fractions. Higher yields of the solid fraction are produced when mix tires are pyrolyzed due to the higher concentration of ash in this type of ELT. Recovered carbon black was characterized by measuring the surface area.

“…Commercial carbon blacks have been reported to have an elemental carbon content of approximately 97.00 wt%. 69 Zhang et al, aer employing the pickling process on pyrolytic char, reported a carbon content increase from 81.79% to 97.18%, thus, making pyrolysis derived char comparable with commercial carbon blacks. 70 TDO is one of the main products of interest when employing thermochemical processes.…”
