Abstract: PROBLEM TO BE SOLVED: To maximize the formation of 1,4-butane diol while minimizing the formation of gamma-butyrolactone by forming a catalyst by making carbon carry palladium, or the like, and bringing this catalyst into contact with hydrogen-containing gas to form a precursor possible to hydrogenate and catalytically hydrogenating this precursor. SOLUTION: A catalyst is formed by making carbon carry all of about 0.1-20 wt.% of palladium, about 0.1-20 wt.% of silver, about 0.1-20 wt.% of rhenium and about 0.1-5 wt.% of at least one of aluminum, cobalt and a mixture of them. 1,4-Butane diol is produced by bringing hydrogen-containing gas into contact with this catalyst to form a precursor possible to hydrogenate and catalytically hydrogenating the precursor. At this time, the precursor is set to at least one compd. selected from maleic acid, succinic acid, gamma- butyrolactone, and the like. By this constitution, the formation of 1,4-butane diol is maximized and the formation of gamma-butyrolactone is minimized.

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.
