Abstract | Improved methods of introducing promoters to catalysts are described. The present invention provides a convenient method of uniformly distributing a catalyst promoter, to provide for intimate contact between the promoter and the active catalyst sites. This intimate contact can enhance the activity and/or product selectivity of the promoted catalyst. In some embodiments, the method includes reacting an alkali metal with an alcohol in a non-aqueous medium, contacting the resulting solution with a starting catalyst, and depositing the alkali metal onto the starting catalyst to form an alkali-promoted catalyst.
L'invention concerne des procédés améliorés d'introduction de promoteurs dans des catalyseurs. La présente invention concerne un procédé pratique de distribution uniforme d'un promoteur de catalyseur, qui permet d'obtenir un contact intime entre le promoteur et les sites actifs du catalyseur. Ce contact intime peut améliorer l'activité et/ou la sélectivité envers le produit du catalyseur contenant le promoteur. Selon certains modes de réalisation, le procédé comprend la mise en réaction d'un métal alcalin avec un alcool dans un milieu non aqueux, la mise en contact de la solution résultante avec un catalyseur de départ, et le dépôt du métal alcalin sur le catalyseur de départ pour former un catalyseur améliorés aux alcali. |
