Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 18 (Septembre 2009) . - pp. 8402–8406 Titre : Catalytic hydrocracking of fresh and used cooking oil Type de document : texte imprimé Auteurs : Stella Bezergianni, Auteur ; Spyros Voutetakis, Auteur ; Aggeliki Kalogianni, Auteur Année de publication : 2010 Article en page(s) : pp. 8402–8406 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Vegetable  oils  Hydrocracking  Cracking  Heteroatom  removal  and  saturation  reaction  mechanisms Résumé : Hydrocracking of vegetable oils is a prominent technology for the production of biofuels. This work compares the product yields and quality of hydrocracking fresh and used cooking oil under nominal operating conditions. Cracking, heteroatom removal and saturation reaction mechanisms are evaluated for both feedstock types and for three typical hydrocracking temperatures. The assessment of both feedstocks indicates that they are both suitable for high diesel yields with smaller kerosene/jet and gasoline/naphtha yields. As temperature increases, diesel selectivity increases for both feedstock types. However, the used oil feedstock exhibits higher kerosene/jet and naphtha selectivity at low temperatures (350 °C) and lower at the highest hydrocracking temperature (390 °C).
