The invention relates to the technical field of regeneration of inactivated aluminum oxide, and discloses a regeneration method of inactivated aluminum oxide and application of the regeneration method. The regeneration method comprises the following steps: (1) contacting inactivated aluminum oxide with a cleaning solvent for cleaning to obtain purified aluminum oxide I; (2) contacting the purified aluminum oxide I with water vapor for purging to obtain purified aluminum oxide II; and (3) contacting the purified aluminum oxide II with alkali liquor for soaking to obtain regenerated aluminum oxide. According to the regeneration method of the inactivated aluminum oxide, the obtained regenerated aluminum oxide is high in activity and low in production cost, the problem of environmental pollution caused by treatment of the inactivated activated aluminum oxide can be effectively reduced, and the regeneration method has good social benefits and is suitable for industrial popularization. 本发明涉及失活氧化铝再生技术领域，公开了一种失活氧化铝的再
