    • PROBLEM TO BE SOLVED: To provide a method for producing a shell catalyst which comprises a porous catalyst support having an outer shell in which at least one catalytically active species is contained.SOLUTION: The method using a device 10 which is adapted to produce a fluid bed of molded catalyst supports by means of a process gas 40, the molded catalyst supports revolving in the bed on elliptical or toroidal orbits. The method comprises the steps of: a) feeding molded catalyst supports to the device 10 and producing a fluid bed of the molded catalyst supports by means of the process gas 40, the molded catalyst supports revolving in the fluid bed on elliptical or toroidal, preferably toroidal, orbits; b) impregnating an outer shell of the molded catalyst supports with a catalytically active species or a precursor thereof by spraying the molded catalyst supports that revolve in the fluid bed on elliptical or toroidal orbits with a solution that contains catalytically active species or a precursor thereof; and c) drying the molded catalyst supports that are sprayed with the solution.
    • 要解决的问题:提供一种制备壳催化剂的方法,其包括具有外壳的多孔催化剂载体,其中含有至少一种催化活性物质。溶液:使用适于产生流体的装置10的方法 通过工艺气体40成型催化剂载体床,模制的催化剂支持在床上以椭圆或环形轨道旋转。 该方法包括以下步骤:a)将模制的催化剂载体输送到装置10,并通过处理气体40产生模制的催化剂载体的流化床,模制的催化剂载体在流化床中在椭圆形或环形上旋转,优选地 环形,轨道; b)用催化活性物质或其前体将模制的催化剂载体的外壳浸入含有催化活性物质或其前体的溶液中的在流化床中旋转的模制催化剂载体在椭圆或环形轨道上; 和c)干燥用溶液喷射的模制催化剂载体。
