The invention relates to a supported catalyst based on palladium-γ-alumina, which is characterized in that the catalyst support material contains 1 to 1000 ppm by mass of sodium oxide and has a specific pore volume of 0.4 to 0.9 ml/g and a BET surface area of 150 to 350 m 2 /g. The invention further relates to a process for hydrogenating polyunsaturated ethers with hydrogen to the corresponding saturated ethers, in which the catalyst used is such a catalyst. |
