Abstract
A hydrogenation reaction catalyst used for a reaction of 1,4-anhydroerythritol and hydrogen to produce 3-hydroxytetrahydrofuran includes a carrier, at least one oxide selected from the group consisting of an oxide of a Group 6 element and an oxide of a Group 7 element, the oxide being supported on the carrier, and a metal other than a Group 6 element and a Group 7 element, the other metal being supported on the carrier. The amount of the oxide supported on the carrier in terms of a metal atom forming the oxide is 0.01 to 10% by weight based on the total amount of the oxide and the carrier being 100% by weight. The molar ratio in terms of metal of the other metal to the Group 6 element and Group 7 element forming the oxide [other metal/Group 6 element and Group 7 element] is 50/1 to 1/4.
