Title:
SELECTIVE HYDROGENATION CATALYST, MANUFACTURING METHOD OF SELECTIVE HYDROGENATION CATALYST, AND SELECTIVE HYDROGENATION METHOD
Document Type and Number:
Japanese Patent JP2019089039
Kind Code:
A
Abstract:
To provide a selective hydrogenation catalyst using no noble metal, capable of controlling alkene selectivity depending on reaction conditions, and providing excellent alkene selectivity, a manufacturing method of the selective hydrogenation catalyst, and a selective hydrogenation method.SOLUTION: A selective hydrogenation catalyst consists of a powder Heusler alloy of Co(MnFe)(GaGe) (0≤x≤1, 0≤y≤0.3). The selective hydrogenation catalyst can be manufactured by arc melting a raw material weighted to be a composition of the Heusler alloy, conducting a homogenization treatment at 700°C to 1100°C for 1 hr. to 80 hr. and pulverizing an alloy after the homogenization treatment. Alkyne can be selectively hydrogenated to alkene by contacting alkyne and hydrogen in the presence of the selective hydrogenation catalyst.SELECTED DRAWING: Figure 1
