A HYDROGENATION REACTION CATALYST PRECURSOR OF THE PRESENT INVENTION COMPRISES A CATALYST CARRIER (A) AND AMETAL OXIDE COMPOSITION (B) CARRIED ON OR MIXED WITH THE CATALYST CARRIER (A) AT A WEIGHT RATIO OF (B)/(A) = 15/85 TO 65/35; THE CATALYST CARRIER (A) COMPRISING A CARRIER BASE MATERIAL OF SILICA, ETC. AND A COATING OF TITANIUM OXIDE AND/OR TITANIUM HYDROXIDE, THE METAL OXIDE COMPOSITION (B) COMPRISING COPPER OXIDE, ZINC OXIDE, AND AT LEAST ONE OXIDE OF A METAL SELECTED FROM THE GROUP CONSISTING OF AN ELEMENT OF GROUP IIA OF THE PERIODIC TABLE, AN ELEMENT OF GROUP IIIB OF THE TABLE, A LANTANIDE ELEMENT, AND AN ACTINIDE ELEMENT AT A WEIGHT RATIO OF 100/(0 TO 25)/(0 TO 25). A HYDROGENATION REACTION CATALYST WITH A HIGH CATALYTIC ACTIVITY AND A HIGH REACTION SELECTIVITY IS OBTAINED BY REDUCTION OF THE HYDROGENATION REACTION CATALYST PRECURSOR. BY THE USE OF THEHYDROGENATION REACTION CATALYST OF THE PRESENT INVENTION, A HIGH QUALITY ALCOHOL CAN BE PRODUCED AT A HIGH YIELD AND WITH A HIGH SELECTIVITY EVEN AT A LOW REACTION TEMPERATURE AND A LOW HYDROGEN PRESSURE. |
