The present invention relates to a silicon-containing alumina support, a process for preparing the support, and a catalyst containing the support. In the present invention, the alumina support includes an additive silicon enriched on its surface, with the difference between the atomic ratio of silicon to aluminum on the surface of alumina support and that of the alumina support is at least 0.10. The process for preparing the silicon-containing alumina support comprises adding a nanometer silicon compound. The inventive alumina support can be used in manufacturing a catalyst for hydrotreating hydrocarbons with good physico-chemical properties and performance.
L'invention concerne un support en alumine contenant du silicium, sa préparation et un catalyseur présentant ledit support en alumine. Dans le support en alumine selon l'invention, le silicium faisant office de co-catalyseur est enrichi sur la surface du support, la différence entre le rapport Si/Al dans la phase superficielle du support en alumine et le rapport moyen Si/Al étant supérieure ou égale à 0,10. Lors de la préparation dudit support en alumine contenant du silicium, un nanomatériau contenant du silicium est ajouté. Le support en alumine selon l'invention peut être utilisé pour produire des catalyseurs adaptés à l'hydrotraitement d'hydrocarbures, présentant des propriétés physico-chimiques et des performances d'usage améliorées.
