    Abstract: A process for producing desulfurized fats and oils or fatty acid esters, which are highly suitable as a starting material for producing alcohols via hydrogenation, at a high yield is disclosed. Desulfurized fats and oils or fatty acid esters are obtained by contacting fats and oils or fatty acid esters with a catalyst represented by the following formula (I) under a hydrogen atmosphere or a mixture of hydrogen with an inert gas: Ni.CuxOy(I) wherein x represents an atomic ratio of Cu determined by referring Ni as 1 and a value of from 0.02 to 8; and y is an atomic ratio of oxygen satisfying the valence requirements of Ni and Cu. A process for producing alcohols using the desulfurized fats and oils or fatty acid esters is also disclosed. A process for producing an alcohols using desulfurized fats and oils or fatty acid esters is also disclosed. According to the process for producing an alcohol of the present invention, an alcohol of a high purity and good qualities can efficiently and effectively be produced.

    Abstract: The present invention provides a hydrogenation catalyst precursor which does not bring about a problem of environmental pollution involved in copper-chromium catalysts and has a high activity, a high durability and a high selectivity as compared with those of conventional copper-iron-aluminum catalysts, a hydrogenation catalyst obtained by reducing the same, and a production process for alcohols using the above hydrogenation catalyst. The hydrogenation catalyst precursor described above comprises copper, iron and aluminum and containing as a principal component a compound oxide of copper, iron and aluminum in which an atomic ratio Cu : Fe : Al is 1 : (0.02 to 0.4) : (1.0 to 4.0) and which has a copper-aluminum spinel structure.

    Abstract: PCT No. PCT/JP94/00077 Sec. 371 Date Jun. 6, 1995 Sec. 102(e) Date Jun. 6, 1995 PCT Filed Jan. 20, 1994 PCT Pub. No. WO95/19844 PCT Pub. Date Jul. 27, 1995A method for preparing a copper-containing hydrogenation reaction catalyst includes the step of reducing a formed precursor of a copper-containing hydrogenation reaction catalyst with hydrogen gas or a mixture of hydrogen and inert gas by liquid phase reduction in a stream of a solvent. The reductive activation is carried out by the two steps of performing the first stage of liquid phase reduction by which the catalyst precursor is activated in the temperature range of from 20 DEG to 140 DEG C. so that at least 10% by weight of the copper oxide contained in the catalyst precursor can be reduced by the time when the temperature passes 140 DEG C., and then performing the second stage of liquid phase reduction by which the catalyst precursor is further activated in the temperature range of from 140 DEG to 250 DEG C. The catalyst thus obtained has markedly improved catalytic activity and selectivity. An alcohol of high quality can be obtained at a high productivity using the catalyst in a fixed bed continuous reaction system.

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.

    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.
