This invention concerns a method for preparing a hydrogenation catalyst system involving the reaction of a group 4 metallocene (A) with a metal hydride or an organometallic compound (B) at a (B)/(A) molar ratio that is larger than 10 followed by the activation of the resulting catalyst mixture with hydrogen at a hydrogen pressure p (in MPa) and at a temperature T (in ° C.), wherein a neutralising agent (C) that is capable of reacting with the compound (B) is added to the catalyst mixturea) either prior to the activation, orb) within t hours from the activation wherein t equals x divided by (p*T*(B)/(A)), and x=10,000,and a process for the hydrogenation of an olefinically unsaturated compound with hydrogen in the presence of a hydrogenation catalyst system obtained by the method of the invention.
