The present invention provides a hydrogenation catalyst effective for hydrogenating 3-hydroxypropionaldehyde to 1,3-propanediol. The hydrogenation catalyst comprises an a-alumina support, nickel, ruthenium, and a promoter. The nickel is deposited on the a-alumina support, and the ruthenium and the promoter are deposited on the nickel and the a-alumina support. The a-alumina support comprises at least 92 wt. % of the catalyst, and the nickel comprises from 1 wt. % to 6 wt. % of the catalyst. The present invention also provides a process of hydrogenating 3-hydroxypropionaldehyde to 1,3-propanediol with the catalyst.
La présente invention concerne un catalyseur d'hydrogénation efficace pour hydrogéner 3-hydroxypropionaldehyde en 1,3-propanediol. Ce catalyseur d'hydrogénation comprend un support d'alumine a, du nickel, du ruthénium et un promoteur. Le nickel est déposé sur le support d'alumine et le ruthénium et le promoteur sont déposés sur le nickel et le support d'alumine a. Le support d'alumine a comprend au moins 92 % en poids de ce catalyseur et le nickel comprend entre 1 % et 6 % en poids de ce catalyseur. Cette invention concerne aussi un processus d'hydrogénation de 3-hydroxypropionaldehyde en 1,3-propanediol avec ce catalyseur.
