Abstract

Disclosed is a method for regenerating a hydrogenation catalyst. More specifically, disclosed is a method for regenerating a hydrogenation catalyst poisoned during hydrogenation of a hydroformylation product for preparation of alcohol by stopping hydrogenation in a hydrogenation stationary phase reactor in which the hydrogenation catalyst is set and flowing hydrogen gas under a high temperature normal pressure. The method has an effect in that the poisoned hydrogenation catalyst can be efficiently recovered through a simple process.
