Evaluation of laboratory methods for the acquisition of catalyst from fischer–tropsch wax/catalyst mixtures / Tie-jun Lin in Industrial & engineering chemistry research, Vol. 51 N° 44 (Novembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 44 (Novembre 2012) . - pp. 14511-14516 Titre : Evaluation of laboratory methods for the acquisition of catalyst from fischer–tropsch wax/catalyst mixtures Type de document : texte imprimé Auteurs : Tie-jun Lin, Auteur ; Meng Xuan, Auteur ; Li Shi, Auteur Année de publication : 2013 Article en page(s) : pp. 14511-14516 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Wax  Catalyst Résumé : Catalyst breakdown by physical attrition and chemical stresses is a problem of great and continuing concern in the slurry phase Fischer―Tropsch Synthesis. To reach a better understanding of the morphology and composition of a working catalyst, it requires first the removal of wax from the catalyst. In this work, Improved Soxhlet Extraction (ISE) in comparison of Standard Soxhlet Extraction was evaluated concerning their separation efficiency and relevancy for characterization of working catalysts. ISE extracted a greater amount of wax and recovered nearly all of the catalyst. In addition, ISE does not change the morphology and particle size distribution of working catalysts whereas Soxhlet extraction fails to reflect the actual information on the catalyst. The ISE is appropriate for the rapid and accurate analysis in plant operation.
