PURPOSE:To prepare a hydrogenation catalyst for preparing an alcohol with high activity and high filtration properties and contg. no chromium by reducing a catalyst precursor wherein copper oxide and zinc oxide obtd. by burning a basic carbonate contg. copper and zinc with hydrogen and oxidizing partially it with an oxygen-contg. gas. CONSTITUTION:A copper- and zinc-contg. insoluble basic carbonate is obtd. by mixing a soluble copper salt-and soluble zinc salt-contg. water soln. with a water soln. contg. an alkaline precipitant. Then, this basic salt is in a water active gas to obtain a catalyst precursor wherein copper oxide and zinc oxide are the ingredients. Then, after this catalyst precursor is reduced with hydrogen, the copper reduced by bringing it into catalytic contact with an oxygen-contg. gas is partially oxidized. A hydrogenation catalyst for preparing alcohol is obtd. thereby. In addition, it is pref. that in the partial oxidation after reduction with hydrogen, 10-80% reduced copper is usually oxidized to copper oxide to afford practical activity and filtration properties. |
