“…The most significant absorption peak of the gaseous products occurred in the range of 2400–2240 cm −1 , indicating the production of CO 2 during pyrolysis. Additionally, the absorption peak in the range of 730–630 cm −1 also indicated the presence of CO 2 24 . The production of CO 2 was minimal at 200°C but gradually increased with temperature until reaching a maximum at 350°C.…”

“…Additionally, the absorption peak in the range of 730-630 cm À1 also indicated the presence of CO 2 . 24 The production of CO 2 was minimal at 200 C but gradually increased with temperature until reaching a maximum at 350 C. The fracture and rearrangement of C O and COOH within the internal structure of biomass were the main contributors to the generation of CO 2 . The production of CO 2 was closely related to the composition of the biomass.…”

To investigate the effective utilization of agricultural and forestry wastes for mitigating the shortage of primary energy and environmental pollution, the pyrolysis behavior of corn straw (CS), wheat straw (WS), and poplar sawdust (PS) was studied using thermogravimetric–Fourier transform infrared (TG‐FTIR) analysis. The activation energies and pyrolysis mechanism functions of different biomass types were calculated. The results showed that the functional group structures of the gaseous products generated from the pyrolysis of different biomass types were similar, mainly including OH, aliphatic CH, CO, aromatic ring skeleton, aromatic CH, and CO groups. These functional group structures mainly existed in oxygen‐containing compounds such as phenols, ketones, aldehydes, acids, esters, alcohols, and ethers. The pyrolysis process of agricultural and forestry wastes exhibited certain differences, with the PS undergoing thermal decomposition more easily, while the thermal decomposition mechanism functions of the two agricultural wastes (CS and WS) were similar. PS had a later initial release time for volatile matter, and the oxygen compounds produced by its pyrolysis were the highest, followed by WS and CS.
