Hydrothermal electrolysis of glycerol using a continuous flow reactor / Yuksel, Asli in Industrial & engineering chemistry research, Vol. 49 N° 4 (Fevrier 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 4 (Fevrier 2010) . - pp 1520–1525 Titre : Hydrothermal electrolysis of glycerol using a continuous flow reactor Type de document : texte imprimé Auteurs : Yuksel, Asli, Auteur ; Koga, Hiromichi, Auteur ; Sasaki, Mitsuru, Auteur Année de publication : 2010 Article en page(s) : pp 1520–1525 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Hydrothermal  electrolysis  Glycerol  Continuous  flow  reactor. Résumé : Hydrothermal electrolysis reactions of glycerol were investigated under various operating conditions to determine the effects of applied DC current, electrolysis time, and alkali concentration on the decomposition mechanism of glycerol. In addition, intermediate products were identified, possible reaction schemes for both hydrothermal electrolysis and hydrothermal degradation of glycerol based on experimental data were clarified, and detailed product analysis was conducted using high performance liquid chromatography (HPLC), gas chromatography with a flame ionization detector (GC-FID), and gas chromatography with a thermal conductivity detector (GC-TCD). For the present study, a continuous flow reactor equipped with titanium electrodes (as cathode and anode), an electric furnace, a heater, a pump, a heat exchanger, a back pressure regulator, and DC supply was used. The main gaseous product was hydrogen, whereas glycolaldehyde, lactic acid, and formic acid were the main liquid products. Results indicate that greater than 92% of the glycerol could be decomposed under optimum conditions by hydrothermal electrolysis using the continuous DEWEY : 660 ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie9016418 [article] Hydrothermal electrolysis of glycerol using a continuous flow reactor [texte imprimé] / Yuksel, Asli, Auteur ; Koga, Hiromichi, Auteur ; Sasaki, Mitsuru, Auteur . - 2010 . - pp 1520–1525.
