Abstract
The present invention relates to a method for regenerating a hydrogenation catalyst for a phthalate compound. More specifically, the present invention regenerates a hydrogenation catalyst for a phthalate compound by using an alcohol, and thereby provides a method for regenerating a hydrogenation catalyst for a phthalate compound that is capable of continuously hydrogenating a phthalate compound without replacing a catalyst in a catalytic reactor, and is also capable of improving operational stability and the lifetime of a catalyst and increasing economic efficiency.
