Influence of secondary reactions on the heat of pyrolysis of biomass / Claudia Gomez in Industrial & engineering chemistry research, Vol. 48 N° 23 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 23 (Décembre 2009) . - pp. 10222–10233 Titre : Influence of secondary reactions on the heat of pyrolysis of biomass Type de document : texte imprimé Auteurs : Claudia Gomez, Auteur ; Enric Velo, Auteur ; Federica Barontini, Auteur Année de publication : 2010 Article en page(s) : pp. 10222–10233 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Influence--Secondary--Reactions--Heat--Pyrolysis--Biomass Résumé : The thermal behaviors during the pyrolysis of two different biomass samples, beech wood from carpentry residuals and artichoke thistle from energy-dedicated crops, were investigated. Thermogravimetry/differential scanning calorimetry (TG-DSC) and thermogravimetry coupled to Fourier transform infrared (TG-FTIR) analysis of evolving products were used to investigate the thermal effects of the pyrolysis process. The role of pretreatments (hot-water washing, ethanol extraction, and their combination) was also analyzed. High alterations in the heat demand were observed as a function of the initial sample mass and pyrolysis conditions. The role of vapor−solid secondary interactions was evidenced by the evolution profiles of the main pyrolysis products.
