Abstract: The present invention discloses a hollow spherical catalyst for a fixed bed with internal fluidization of particles and a method for preparing the same. The preparation method used in the present invention is characterized in: fully mixing precious metal nanopowder with an organic oil phase to form an internal oil phase; preparing a gel ball of an oil-in-water structure by taking an aluminum oxide molding solution as an outer aqueous phase using an independently researched and developed coaxial dual-dropper forming apparatus; and then preparing a hollow aluminum oxide catalyst containing precious metal powder from the gel ball through processes of aging, calcination, and reduction. The resulting catalyst is expressed as X@Al2O3, where the precious metal nanopowder X is wrapped inside hollow Al2O3, and the catalyst has an outer diameter of 1.5-5.0 mm, a shell pore diameter (aluminum oxide) of 10-50 nm, and the precious metal nanopowder sized 200-500 nm. When the catalyst is used in a fixed bed, the reactant and product molecules diffuse into and out of the catalyst smoothly and fully contact with precious metal components, forming a micro-fluidization reaction system, thus realizing complementary advantages of an existing fixed-bed catalyst and a fluidized-bed catalyst, and reducing losses of active components of the precious metal.
