ABSTRACT:
A hydrogenation reaction catalyst precursor of the present invention comprises a catalyst carrier (A) and a metal 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 lanthanide 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 the hydrogenation 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.
