Molecular characterization of gasoline and diesel streams / Yongwen Wu in Industrial & engineering chemistry research, Vol. 49 N° 24 (Décembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 24 (Décembre 2010) . - pp. 12773-12782 Titre : Molecular characterization of gasoline and diesel streams Type de document : texte imprimé Auteurs : Yongwen Wu, Auteur ; Nan Zhang, Auteur Année de publication : 2011 Article en page(s) : pp. 12773-12782 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Gasoline  Diesel  Streams Résumé : A novel methodology to characterize gasoline and diesel streams into the molecular level is developed on the basis of molecular type homologous series (MTHS) matrix framework (Chem. Eng. Sci. 2005, 60, 6702−6717). The method comprises the enhancements of both representation matrix construction and transformation methodology of bulk properties into molecular composition. To improve the accuracy and adequacy of the representation model, different strategies are set up separately for gasoline and diesel streams for the consideration of isomers. By introducing statistical distribution and applying extensive bulk properties, the transformation approach is revolutionized to increase the usability, and tackle the challenge of possibly achieving significantly different molecular compositions from the same bulk properties of refining streams by existing transformation approaches. The proposed method is verified with both gasoline and diesel streams, and the results show a good agreement with measured data.
