Regenerierungsverfahren eines Hydrierungskatalysators und Verfahren zur Hydrierung von nitrilfunktionellen Verbindungen |
摘要 |
<p>The invention concerns a method for regenerating a hydrogenation catalyst, and hydrogenation methods carried out with a catalyst comprising at least one regenerated catalyst. More particularly, it concerns a method for regenerating Raney catalysts used in total or partial hydrogenating processes of compounds comprising nitrile functions into amine functions. Said method consists in treating the spent catalyst with a basic solution and optionally in subjecting said catalyst to hydrogenation before stripping to eliminate the impurities present on the catalyst. Thus, the regenerating method enables to recuperate up to 100% of the catalytic activity.</p> |
