This invention discloses an inlet diffuser, comprising: a sleeve consisting of an inner cylinder and an outer cylinder arranged coaxially, the bottom end of the inner cylinder being higher than the bottom end of the outer cylinder, with a liquid-holding zone between the inner and outer cylinders; an annular bottom plate coaxially connected to the bottom end of the outer cylinder, forming a liquid phase channel between the annular bottom plate and the inner cylinder, the area of ​​the liquid phase channel being less than or equal to the area of ​​the liquid-holding zone; a top cover disposed above the inner cylinder, forming a gas phase channel between the top cover and the inner cylinder; a rotating shaft coaxially inserted into the inner cylinder; at least one layer of helical blades disposed within the inner cylinder and driving the rotating shaft to rotate; and at least one layer of splash plates, which have a downward-opening conical structure, and the splash plates are linked to the lower end of the rotating shaft. This invention also discloses a hydrogenation reactor. In the inlet diffuser of this invention, the gas phase enters the inner cylinder, blowing the helical blades and driving the splash plates to rotate, providing an initial horizontal velocity to the liquid phase, and covering the entire reactor cross-section with a spray area.
