<p>PURPOSE: A method for preparing a homogeneous supported catalyst for carbon nanotubes (CNT) and a device for the same are provided to obtain a granular catalyst and to prevent the reduction of catalytic activity caused by the complete drying of a solvent. CONSTITUTION: A method for preparing a homogeneous supported catalyst for CNT comprises the steps of: obtaining a metal homogeneous aqueous solution by successively mixing a precipitation suppressive component and a precursor aqueous solution of a catalytic component with a precursor aqueous solution of an active component; obtaining a mixture by mixing the metal homogeneous aqueous solution with a support and impregnating the mixed product; and obtaining a granular catalyst by allowing the mixture to undergo a rapid drying process at least two times, mixing the rapidly dried product with metal or ceramic balls, and additionally drying the mixed product.</p> |
