A method of treating a catalyst support comprises introducing onto and/or into an untreated catalyst support which is partially soluble in an aqueous acid solution and/or a neutral aqueous solution, Si, Zr, Cu, Zn, Mn, Ba, Co, Ni and/or La as a modifying component. The modifying component is capable, when present in and/or on the catalyst support, of suppressing the solubility of the catalyst support in the aqueous acid solution and/or the neutral aqueous solution. A protected modified catalyst support which is less soluble or more inert in the aqueous acid solution and/or the neutral aqueous solution, than the untreated catalyst support, is thus formed. A method of forming a catalyst from the modified catalyst support is also provided.
La présente invention concerne un procédé permettant de traiter un support de catalyseur, lequel procédé consiste à introduire sur et/ou dans un support de catalyseur non traité partiellement soluble dans une solution aqueuse acide et/ou une solution aqueuse neutre, du Si, Zr, Cu, Zn, Mn, Ba, Co, Ni et/ou La comme composant modificateur. Le composant modificateur est capable, lorsqu'il est présent dans et/ou sur le support de catalyseur, de supprimer la solubilité du support de catalyseur dans la solution aqueuse acide et/ou la solution aqueuse neutre. On obtient de cette manière un support de catalyseur modifié protégé qui est moins soluble ou plus inerte dans la solution aqueuse acide et/ou la solution aqueuse neutre que le support de catalyseur non traité. L'invention se rapporte également à un procédé permettant de former un catalyseur à partir du support de catalyseur modifié.
