PURPOSE:To obtain the catalyst having high activity and selectivity at low temp. and having a long service life by incorporating the oxides of >=1 kind among copper, zinc and chromium and nickel oxide into a porous carrier. CONSTITUTION:The oxides of >=1 kind among copper, zinc and chromium and nickel oxide are incorporated into a porous carrier to obtain the desired catalyst. Diatomaceous earth, alumina, silica, etc., are used for the porous carrier. An aq. soln. of the metal compds. and porous carrier is mixed with the hydroxides of alkali metal elements as a precipitant to form the precipitate, and the precipitate is dried and calcined to prepare the desired catalyst. |
