Abstract: PROBLEM TO BE SOLVED: To provide a process for maximizing the production of 1,4-butanediol. SOLUTION: This process for producing 1,4-butanediol contains a process for bringing a precursor capable of being hydrogenated into contact with a hydrogen-containing gas and a hydrogenation catalyst to catalytically hydrogenate the precursor. The hydrogenation catalyst contains at least one of the group VIII noble metals and at least one of rhenium, tungsten and molybdenum deposited on a carbon carrier. The carbon carrier is brought into contact with an oxidizing agent selected from nitric acid, hydrogen peroxide, sodium hypochlorite, ammonium persulfate and perchloric acid, before the metal is deposited.
