SHELL CATALYST, PRODUCTION METHOD THEREOF AND USE THEREOF

摘要

<P>PROBLEM TO BE SOLVED: To provide a shell catalyst which contains Ni, Cu and/or Pd and further Mn and/or Mo or contains Ni, Mn and Mo and has an open-pore catalytic carrier with a shell and to provide a method for producing the shell catalyst and use of the shell catalyst when hydrogenation is performed. Ž<P>SOLUTION: A production method of the shell catalyst comprises the steps of: forming a fluidized bed of the carrier by using a gas; fluidizing the carrier on an elliptical or circular route; spraying a solution of a catalytic metal compound toward the fluidized carrier; drying the metal compound-sprayed carrier; firing the dried carrier; and changing an oxidation state of a metal component of the sprayed metal compound to the oxidation state of zero.
