Abstract
The invention relates to a novel catalyst for hydrogenation for hydrogenating at least one of dicarboxylic acid or its acid anhydride. The catalyst for hydrogenation according to a first embodiment is obtained by supporting at least one of palladium or platinum, and cobalt on a carrier, and subjecting the resulting carrier to a reduction treatment at 400 K or higher. The catalyst for hydrogenation according to a second embodiment is obtained by supporting at least one of palladium or platinum, and molybdenum on a carrier, and subjecting the resulting carrier to a reduction treatment at 500 K or higher.
