PROBLEM TO BE SOLVED: To solve the problem that the fluidized state of a hydrogen gas and liquid benzene becomes non-uniform because a reaction pipe is non-uniformly filled with catalyst particles, in a perfusate type fixed bed reactor being one embodiment of a conventional hydrogeneration apparatus and reaction is not performed because the contact of the catalyst with a substrate is not performed at a certain part in the reaction pipe and, therefore, the utilization efficiency of a catalyst is low and, further, the optimum reaction temperature Topt required for achieving a high reaction speed is not prescribed especially. SOLUTION: In this hydrogenation apparatus, the temperature of a monolithic catalyst is held to the optimum reaction temperature higher than the boiling point of a dehydrogenation reaction product, and the reaction product is uniformly supplied to the upper part of the monolithic catalyst from a despersion device in each of stages. A required amount of a hydrogen gas is uniformly supplied to the upper part of the monolithic catalyst of the first stage from a hydrogen gas supply part, and the supply volume ratio of the hydrogen gas and the reaction product is regulated in each stage to perform hydrogenation reaction.
