【発明の名称】着磁した水素化反応用ニッケル流動床触媒及びこの触媒の使用方法
Document Type and Number:
Japanese Patent JP3501796
Kind Code:
B1
Abstract:
To provide a magnetized nickel fluidized bed catalyst for hydrogenation reaction having sufficiently high catalytic activity, excellent in settling properties, easily separated, recovered and recycled and reduced in the lowering of settling properties even if used repeatedly.
A magnetic metal fluidized bed catalyst comprises nickel particles, of which the crystal size in a crystal lattice surface (111) by an X-ray diffraction method is 5.0-10.0 nm and/or cobalt particles of which the crystal size is 2.0-10.0 nm and magnetized by applying a magnetic field with a magnetic flux density of 0.1×10-4-30 T to the catalyst. When the magnetized catalyst is used in liquid phase reaction, it shows a sufficient catalytic effect, can easily settle and is recovered after reaction and the recovered catalyst can be used repeatedly.
