METHOD FOR REGENERATING HYDROGENATION CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently regenerating a hydrogenation catalyst the performance of which is deteriorated due to the usage on an industrial scale of an ethylene plant or the like.

SOLUTION: The method for regenerating the hydrogenation catalyst used when alkene is produced by hydrogenating alkyne comprises the steps of introducing steam and oxygen and treating the used hydrogenation catalyst at high temperature of 300-500°C.
