Beschreibung
Zusammenfassung:	The present invention is generally related towards methods for preparing and using a more stable synthesis catalysts. In particular, the present invention is directed towards treating synthesis catalysts with low levels of oxygen to deactivate the smaller more unstable metal crystallites present in the catalyst matrix. The process can be carried out either prior to and/or simultaneously with the synthesis reaction. L'invention concerne en général des procédés de préparation et d'utilisation de catalyseurs de synthèse à stabilité améliorée. L'invention concerne en particulier le traitement de catalyseurs de synthèse à faibles teneurs en oxygène afin de désactiver les plus petites cristallites métalliques les moins stables présentes dans la matrice du catalyseur. Ce procédé peut être mis en oeuvre préalablement et/ou simultanément à la réaction de synthèse.
