Abstract
The invention relates to a novel supported catalyst comprising a combination of metals with nickel as component (a), a metal having an atomic number greater than 43 from Group VIII of the Periodic Table as component (b) and rhenium as component (c) in a weight ratio of (a):(b):(c) of about 10-90:0.05-5:0.03-10 and to the use of the catalyst for high pressure hydrogenation reactions, particularly for the hydrogenation of butanediol product containing aldehyde, butynediol and color forming impurities.
