Analysis of gaseous and liquid products from pressurized pyrolysis of flax straw in a fixed bed reactor / Mohammad Shahed Hasan Khan Tushar in Industrial & engineering chemistry research, Vol. 49 N° 10 (Mai 2010)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 10 (Mai 2010) . - pp. 4627–4632 Titre : Analysis of gaseous and liquid products from pressurized pyrolysis of flax straw in a fixed bed reactor Type de document : texte imprimé Auteurs : Mohammad Shahed Hasan Khan Tushar, Auteur ; Nader Mahinpey, Auteur ; Pulikesi Murugan, Auteur Année de publication : 2010 Article en page(s) : pp. 4627–4632 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Gas Liquid Résumé : Pyrolysis of flax straw was investigated under a nitrogen atmosphere using a tubular reactor at different pressures, ranging from 10 to 40 psi. The effects of pressure on the pyrolysis yields and the products obtained (gas, liquid, char) have been analyzed. The gaseous products were analyzed by online GC, and the bio-oils were characterized by gas chromatography/mass spectrometry (GC/MS). Scanning electron microscopy (SEM) was used to view the char surfaces in order to characterize the char and validate the presence of porosity. As the pyrolysis pressure increased, the yield of char and liquid decreased while the gas products increased. The gas products were mainly CO, H2, CO2, CH4, and C3’s. The bio-oils were mostly composed of phenolic compounds, carboxylic acids, and furfural. The pH and the density of the bio-oil revealed a moderate increase with increasing pressure. The SEM study confirms the porous nature of the char. Overall, bio-oil production was maximized at 10 psi; however, char and hydrogen production was maximized at 20 psi.
