PROBLEM TO BE SOLVED: To provide a catalyst for obtaining an olefin with a high selectivity by using an adjacent diol as a raw material. Kind Code: A1 A catalyst used in a reaction for producing an olefin by reacting a polyol having two adjacent carbon atoms with a hydroxy group and hydrogen, which comprises a carrier and a Group 6 element supported on the carrier. At least one oxide selected from the group consisting of oxides and oxides of Group 7 elements, and at least one metal selected from the group consisting of silver, iridium, and gold supported on the carrier. A catalyst for an olefination reaction, which comprises: [Selection diagram] None |
