“…This can be seen from the TGA curve of SBR composite 43 . Figure 8 confirms that SBR/FOSM‐4 will produce alkanes (2941, 2869, 1498 cm −1 ), 44 alkenes (3069, 1604 cm −1 ), 43 aromatics (693 cm −1 ), 45 NH 3 (3304, 947 cm −1 ), 46 CO 2 (2302 cm −1 ), CO (2174 cm −1 , 2102 cm −1 ), 33 H 2 O (3735 cm −1 ) and other gaseous products during pyrolysis. As we all know, according to the Lambert–Beer law, 47 the absorption intensity of a functional group is proportional to the concentration of the gas product containing the functional group.…”

“…However, the NH group in Figure 8 is very insignificant. It may be because the N content in SBR/FOSM‐4 is below the detection limit, and other functional groups interfere with the N detection 44 . It can be seen from Table 1 that the content of MQAS as N source in SBR/FOSM‐4 is low.…”

“…The yield of limonene followed the same trend; that is, the maximum yield was obtained in the pyrolysis of synthetic rubber. Similar results were obtained by Singh et al , in the pyrolysis of different automotive waste tires and by Tang and co-workers in the pyrolysis of waste rubber and polyurethane bicycle tires.…”

“…40 Pyrolytic gas produced from waste rubbers has a caloric value range of 29.9-42.1 MJ m À3 (ref. 41) and is abundant in alkanes; alkenes; aromatics; acids, and sulphides, 42 with aliphatic compounds (chain alkenes and cyclic alkenes), and aromatics (toluene, xylene, styrene) being the most dominant by 70% and 13.1% respectively. 43 The presence of alkenes, cyclohexenes, and aromatics is attributed to the tyres's decomposition of natural rubber.…”
