The invention discloses a catalyst hydrothermal ageing device and an ageing method. The device comprises a water measuring system, a fluidizing gas system, ageing reactors, a liftable heating system and a condenser; an outlet of the water measuring system is communicated with an outlet of the fluidizing gas system and then is communicated with a feeding pipe of each ageing reactor; a gas outlet pipe of each ageing reactor is communicated with an inlet pipe of the condenser; the number of the ageing reactors is more than or equal to 2; each ageing reactor comprises a settling section, an ageing section and a pre-distribution section from top to bottom; each ageing reactor comprises a reactor top cover and a reactor cylinder body; a plurality of gas outlet pipes are formed in the reactor top cover; filters are arranged in the gas outlet pipes; the cross sectional area of each reactor cylinder body is gradually shrunk from top to bottom. The device can perform hydrothermal ageing treatment on a plurality of samp
