This study systematically investigated the pyrolysis characteristics and product distribution of peeled cotton stalks using thermogravimetry/Fourier transform infrared analysis (TG-FTIR) at heating rates ranging from 5 to 60 K/min. Kinetic parameters were estimated using the two model-free methods, and the results revealed that the activation energy for pyrolysis varied between 182.97 and 213.11 kJ/mol. The three-component parallel reaction model, combined with the Shuffled Complex Evolution algorithm, was applied to perform inverse modeling of the experimental data. The corresponding exact kinetic parameters for independent hemicellulose, cellulose and lignin were obtained. The results revealed that the predicted values based on the optimized kinetic parameters were in good agreement with the experimental data. Ultimately, the blind prediction of the experimental curves at extra heating rates further confirmed the precision and suitability of the optimized kinetic parameters. The FTIR analysis indicated that the absorption spectra related to the peaks remained largely consistent at various heating rates. The evolution patterns of the gas components aligned with the trends observed in the derivative thermogravimetric curves, with the produced gases in the following order: CO₂, formaldehyde, methanol, CO, and finally methane.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"198 ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143783869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil samples collected in autumn 2014 and spring 2015 revealed significant seasonal and crop-specific impacts on soil health indicators.

Sida contributed to the highest dehydrogenase activity, indicating robust microbial activity, alongside increased organic nitrogen (4.92 mg kg⁻¹) and total nitrogen levels (17.0 mg kg⁻¹) in spring. Soil respiration and electrical conductivity varied by season, with pH values slightly higher in spring. Across all crops, nitrogen forms (nitrate, ammonium, and organic nitrogen) were generally higher in spring than autumn, highlighting seasonal dynamics. Yield stability was greatest in giant reed (2.01 kg m⁻² on average), while miscanthus and sida averaged 1.62 and 0.86 kg m⁻², respectively.

Two temperatures (210 °C and 250 °C) were tested and recycling of the liquid fraction was studied to improve the quality of the resulting hydrochar. The hydrochars obtained at 210 °C fulfill the criteria to be used as solid biofuels (ISO 17225–8:2023). Increasing the reaction temperature led to a dramatic reduction of hydrochar yield (from 50 to 20 %) in conventional HTC (with tap water), accompanied by a moderate improvement of higher heating value (HHV, 18.2–20.4 MJ/kg), which decreased the energy yield (from 52.2 % to 23.8 %). Process water recycling significantly improved the hydrochar yield, reaching more than 80 % and 55 % at 210 °C and 250 °C, respectively, because of the formation of secondary hydrochar. C content and HHV also increased, giving rise to substantially higher energy recovery, which surpassed 93 % after four recycling tests at 210 °C. Fouling and alkali indexes of hydrochars showed much lower values than those of the feedstock mainly attributed to the solubilization of Na and K. At 210 °C, process water recycling favored a further reduction of those indexes. N and P were largely transferred to the liquid fraction, particularly the latter. Zn and Cu were, by far, the most abundant heavy metals in hydrochars, with a Zn content being slightly above the value established in Decision (EU) 2022/1244 for their application as a soil amendment.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"198 ","pages":"Article 107854"},"PeriodicalIF":5.8,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrolysis proves to be a viable option, but the recovered product profile is not desirable in terms of quality and value. Date Pits (DP), a waste byproduct chemically rich with lignocellulosic fragments, can provide unique carbon-rich precursors which are highly desirable in the pyrolysis process. This study aims to investigate the synergistic effect of DP addition on PLA pyrolysis products. Thermogravimetric data demonstrates that PLA mixing with DP promotes char formation, initiates degradation at lower temperatures, and decreases the peak decomposition temperature (T_p) from 362 °C to 343 °C. Primary pyrolysis occurs in the range of (200–400 °C) with 75.5 % weight loss and low heating rate shifts T_p toward lower temperatures by averting the development of the thermal lag effect. Chemical structure analysis through FTIR shows that DP addition promotes controlled volatile release through PLA depolymerization hence yielding more uniformed and distinguished peaks for hydroxyl, phenols, and ester-containing groups. Moreover, it promoted free radical reactions that enhanced lactide recovery by restricting aldehyde formation. GCMS profiling indicates that pure PLA pyrolysis majorly yieldes lactide (3,6-Dimethyl-1,4-dioxane-2,5-dione). While the copyrolysis with date pits diversifies this product profile with the production of hydrocarbons (heptane and decane), aromatics (xylene, toluene and styrene), and furans which are highly valued in biorefineries, as drop-in fuels and in petrochemical industries.
