months. Catalyst regeneration is performed by: (a) isolating the catalyst from the glovebox, (b) exposing the catalyst to a stream of hydrogen and heating it, (c) evacuation of the catalyst, and (d) refilling of the catalyst with inert gas and reconnecting it to the box. The mixture of 5% H2 in N2 (uncertified) is used as a regeneration gas.
