“…Moreover, it was also shown [70] that promotion with Pt and Ru resulted in more unstable cobalt alumina catalysts which deactivated more rapidly in the presence of FT reaction feed and products. Holmen et al [37] also observed more rapid deactivation of CoRe/Al 2 O 3 than monometallic Co/Al 2 O 3 catalysts.…”

Résumé-Promotion par les métaux nobles de catalyseurs Fischer-Tropsch à base de cobalt : une revue -La synthèse Fischer-Tropsch est une part essentielle du procédé XTL (X-To-Liquids, avec X = Gaz, Biomasse ou Charbon) qui convertit du gaz de synthèse en hydrocarbures pour carburants propres. Les catalyseurs à base de cobalt supportés sur des oxydes inorganiques constituent le meilleur compromis pour la production de paraffines à longues chaînes carbonées et de cires. L'efficacité du procédé FischerTropsch dépend très fortement de la performance du catalyseur à base de cobalt. La promotion de ce catalyseur par des métaux précieux peut très fortement améliorer ses performances. Cet article fait la revue des différents effets des métaux nobles sur la structure et la performance de catalyseurs à base de cobalt. Les impacts sur le coût et l'activité des catalyseurs apparaissent comme des éléments incontournables dans le design de catalyseurs performants pour la synthèse Fischer-Tropsch.

“…Dispersion and reducibility of supported cobalt catalysts is usually estimated using H 2 chemisorption and O 2 titration technique. Depending on cobalt loading, the reducibility values for unpromoted alumina based catalysts commonly vary between 10 to 45% (Jacobs et al, 2002;Borg et al, 2007). The temperature, 350°C, is Calcination temperature (°C) widely adopted as the standard reduction temperature of supported cobalt catalysts for these analyses.…”

“…Ru is the most studied noble metal promoter and it has been frequently showed to play a role both in structural and electronic promotion. 146,149,155,157,[160][161][162][163][164][165][166][167][168]170,174,176,177,254,260 In the early nineties, Turney et al observed that the addition of Ru to Co/CeO 2 catalysts drastically increased the Co F-T activity without modifying the catalyst selectivity. 44,45 Results obtained from XPS and TPR indicated that Ru caused a decrease of the reduction temperature of supported Co 3 O 4 nanoparticles.…”
