REDUCING CATALYST, ITS MANUFACTURING METHOD AND SELECTIVE HYDROGENATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reducing catalyst excellent in handling, safety end durability and capable of performing hydrogenation reaction selectivity, its manufacturing method and a selective hydrogenation method.

SOLUTION: This reducing catalyst 10 is obtained by impregnating a carrier 2 having a large amount of voids with a transition element ions-containing solution and holding the impregnated carrier 2 in a hydrogen gas to reduce the transition element ions.
