The invention discloses a hydrogenation method of reformate. Reformate is subjected to hydrorefining before entering a depentanizer; a liquid-phase hydrotreating technology is adopted for hydrorefining; a pipeline for introducing one part of feedstock of a reformer warmed through a heat exchanger into a hydrorefining reactor is arranged; and one part of feedstock of the reformer is introduced into a hydrogenation reactor at early starting of the hydrogenation reactor, introduction of the feedstock of the reformer is stopped after a period of time and the reformate is introduced into the hydrorefining reactor for the normal hydrorefining reaction process. According to the method, stable and qualified quality of a reaction product at early starting can be ensured.
