The catalytic properties of a model PtCo/silica catalyst tested with this prototype have shown to be in the same range of those obtained in similar conditions with classical fixed-bed reactors. No bulk cobalt oxidation nor sintering were observed on operando XRD patterns. The formation of linear carbonyls and adsorbed hydrocarbons species at the surface of the catalyst was observed on operando DRIFT spectra. The surface of the catalyst was also suspected to be covered with carbon species inducing unfavorable changes in selectivity. 3 Oil and Gas Science and Technology 70 ARTICULO Scalbert, Julien 54888 Clémencon, Isabelle 54889 Lengens, Christele 54890 Diehl, Fabrice 54891 Decottignies, Dominique 54892 Maury, Sylvie 54893 189207 189207 0 0 0 0 257026 BAAB BAAB 2026-03-06 200061439 0 200061439 2026-03-06 00:19:25 2026-03-06 ARTICULO
