ABSTRACT:
A method for forming a pelletized catalyst having improved stability during a hydrogenation process such as the hydrogenation of a nitrile to an amine, includes the steps of mixing a metal having a melting point below about 400.degree. C. or a hydrogen reducible compound of the low melting point metal with at least one material which is an effective hydrogenation catalyst, and then compressing the mixture to form a pellet. This pellet can then be heated in a stream of gas comprising hydrogen at a temperature above the melting point of the metal. The pellet is then cooled and can then preferably be exposed to air or other oxygen containing gases. Preferred low melting point metals include cadmium and tin. Preferred hydrogenation catalysts include nickel and cobalt either alone or with other metals and metal compounds.
