    Abstract: A process for producing a hydrogenation reaction catalyst precursor is disclosed, including the steps of: (i) coating the outer surface of at least one of a first titanium oxide and a first titanium hydroxide having an outer surface area of at least 15 m2/g with at least one of a second titanium oxide and a second titanium hydroxide formed by hydrolyzing at least one of a titanium alkoxide represented by Formula (I) and a titanium alkoxo acid represented by Formula (II) to prepare a catalyst carrier (A); Ti(OR)4(I) wherein R represents an alkyl group having from 1 to 18 carbon atoms or an aryl group, H2[Ti(OR)6](II) wherein R has the same meaning as above; (ii) applying a metal oxide composition (B) onto the catalyst carrier (A) obtained in step (i), or mixing the metal oxide composition (B) with the catalyst carrier (A) to obtain a hydrogenation reaction catalyst precursor. Also, a process for producing an alcohol is described, including catalytically reducing an organic carboxylic acid ester with hydrogen in the presence of a catalyst obtained by reducing the hydrogenation reaction catalyst precursor produced by the process described above.

    Abstract: A process for producing alcohols comprising catalytically reducing fats and oils or fatty acid esters with hydrogen in the presence of a catalyst for ester reduction is disclosed, wherein the starting oils are first treated at a temperature of from 50 DEG to 200 DEG C. in hydrogen gas or a mixed gas of hydrogen and an inert gas in the presence of a nickel catalyst to yield a sulfur content at not more than 0.6 ppm an acid value (KOH mg/g) of not more than 2. By use of the thus purified starting oils, the catalyst for ester reduction exhibits a prolonged duration.

    Abstract: A process for producing an unsaturated alcohol wherein the catalytic activity and the capability of maintaining double bond are sustained for a long time and side-reactions are suppressed. An unsaturated alcohol is obtained by hydrogenating an alkyl or alkenyl ester of an unsaturated fatty acid or a triglyceride having a long-chain aliphatic unsaturated hydrocarbon group in the presence of a catalytic composition which is a composite metal oxide consisting of (a) zinc oxide and (b) oxide(s) of at least one metal selected from the group consisting of the elements of the group 3A in the periodic table and having a weight ratio of (a)/(b) of from 1/0.01 to 1/1.2.
