PURPOSE:To produce the title catalyst stable from the low to high reaction temps. and having high selectivity by incorporating the water-soluble compds. of copper, Ni, and Al to be converted into metals or metal oxides by the hydrolysis and subsequent baking into a precipitate, and baking and reducing the mixture. CONSTITUTION:The water-soluble compds. of copper, Ni and Al to be converted into the respective metals or metal oxides by the hydrolysis and subsequent baking are incorporated into the precipitate by any of the following means (a)-(c), and the mixture is baked and reduced. (a) The aq. soln. of the above- mentioned three kinds of compds. is added with an alkali to obtain the precipitate. (b) An alkali is added respective to an aq. soln. of the two kinds among the three kinds. of compds. and a soln. of the remaining one kind and the one kind between the above-mentioned two kinds to form precipitates, and both precipitates are closely mixed. (c) An alkali is respectively added to the aq. solns. of each kind among the three kinds to form precipitates, and the precipitates are closely mixed. |
