Abstract
Official abstract text for this publication.
A catalyst for a hydrogenation reaction including: a polymer support; and a catalytic component supported on the polymer support. The polymer support comprises a repeating unit represented by Formula 1.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for manufacturing alkene, the method comprising: hydrogenating alkyne under a catalyst for a hydrogenation reaction to manufacture alkene, wherein the catalyst comprises a polymer support and a catalytic component comprising one or more of platinum, palladium, ruthenium, iron, nickel, cobalt, molybdenum, gold, silver, copper, titanium, gallium, cerium, aluminum, zinc, and lanthanum supported on the polymer support, wherein the polymer support consists of a repeating unit represented by any one of the following Chemical Formulae 2 to 9, and wherein the polymer support has a weight average molecular weight of 25,000 g/mol to 50,000 g/mol: wherein in the Chemical Formulae 2 to 9, means a point of attachment between the repeating units, and a terminate group is a hydrogen atom. 2 . The method of claim 1 , wherein an amount of the catalytic component is 0.01 wt. % to 10 wt. % based on a total weight of the catalyst for a hydrogenation reaction. 3 . The method of claim 1 , wherein the alkyne is acetylene, propyne, butyne, pentyne, hexyne, heptyne or octyne.
