Title:
SELECTIVE HYDROGENATION OF ALKYNE-CONTAINING FEED
Document Type and Number:
Japanese Patent JP3866318
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for hydrogenating a feed containing a 2-6C alkyne further additionally containing a sulfur compound into the corresponding alkene in the presence of a supported palladium catalyst promoted by an alkali metal fluoride.
SOLUTION: This method is to selectively hydrogenate at least one kind of alkyne containing 2-6 carbon atoms per molecule and further at least one kind of sulfur compound as an impurity (preferably acetylene) into at least one kind of the corresponding alkene (preferably ethylene) having 2-6 carbon atoms using hyderogen gas. A feed together with the hydrogen gas is brought into contact with a catalyst containing palladium, at least one kind of alkali metal fluoride and an inorganic support. The catalyst preferably contains silver or its compound. The presently preferred alkali metal fluoride is potassium fluoride.
