Device and method for preparing activated carbon loaded metal palladium catalyst

The invention discloses a device and a method for preparing an activated carbon supported metal palladium catalyst. The preparation method of the activated carbon supported metal palladium catalyst comprises the following steps: filling activated carbon into a first adsorption column; preparing a palladium chloride aqueous solution in a preparation kettle; the palladium chloride aqueous solution is sent to the first adsorption column through a circulating pump, passes through the first adsorption column, passes through a first liquid outlet and then returns to the preparation kettle through a first liquid outlet pipeline, and the operation is repeated for multiple times; a reducing agent is introduced into the first adsorption column for reduction; distilled water is added into the preparation kettle, the distilled water is conveyed to the first adsorption column through the circulating pump, the distilled water passes through the first adsorption column, passes through the first liquid outlet and then return
