In Tammann’s method, crystal nuclei are formed at a given nucleation temperature and are grown up to macroscopic sizes at a higher development temperature. The effects on the number and sizes of the clusters caused by heating from the nucleation to the growth temperature are widely neglected there. The number and sizes of the crystals are typically determined by microscopy. The stepwise crystallization approach employs calorimetry for similar purposes. Instead of the second (development) stage of Tammann's method, stepwise crystallization analyzes the thermal effects evolving during the heating stage. A comparison of the magnitudes of the cold crystallization enthalpy registered during heating of the samples after isothermal (annealing) stage allows estimating the amount of crystal nuclei. Dependence of the magnitude of cold crystallization enthalpy on the annealing time provides in this way information on the nucleation kinetics of the respective material. The parametrization of kinetics is typically performed by fitting experimental data with Kolmogorov-Johnson-Mehl-Avrami type equations. The interpretation of the resulting parameters is not straightforward because the magnitude of cold crystallization effects depends not only on the sample state but also on the heating conditions.

This study explores the co-pyrolysis of maize cob with dehydrochlorinated PVC, focusing on product yields, chlorine distribution, and thermal interactions. Virgin PVC was dehydrochlorinated at 593 K, achieving 99 % chlorine removal, and its thermal behaviour was assessed using thermogravimetric analysis (TGA) coupled with Fourier transform infrared spectroscopy (FT-IR). For the three heating rates studied: 5, 10 and 30 K/min, HCl was the main compound released up to 593 K. Lab-scale co-pyrolysis experiments were conducted in a fixed-bed reactor at 873 K with varying biomass-to-PVC mass ratios. Increasing the PVC content enhanced oil yield and aromatic compound formation, slightly increased char carbon content, and redistributed chlorine predominantly into the oil phase. The gas phase was enriched with hydrocarbons such as methane, ethene, and ethane. The results indicate that dehydrochlorinated PVC alters biomass pyrolysis pathways, promoting deoxygenation reactions and reducing char formation. These findings provide insights into optimizing co-pyrolysis conditions for improved product quality, demonstrating the potential of dehydrochlorinated PVC as a carbon-rich additive for thermochemical biomass conversion.</div></div>","PeriodicalId":23058,"journal":{"name":"Thermochimica Acta","volume":"749 ","pages":"Article 180023"},"PeriodicalIF":3.1,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143936964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
