Example Embodiment
[0013] [Example 1]
[0014] Catalyst 1 uses proper amount of Mg(NO 3 ) 2 The solution is immersed in an equal volume, and then calcined at 600℃ to obtain MgO-modified Al 2 O 3 The carrier is crushed and mixed with water to be beaten to obtain slurry I. The required amount of the mixed solution of copper nitrate, zinc nitrate and manganese nitrate and 1.0 mol / L sodium carbonate aqueous solution are simultaneously dropped into the slurry I for co-precipitation to form a slurry II. The precipitation temperature is 70℃, the pH value of the solution is controlled to be 8.0, the solution is aged at 70C for 4 hours after dripping, then the precipitate is washed and filtered, dried at 120℃ for 12 hours, calcined at 350℃ for 4 hours, tableting Molded to obtain catalyst 1 (the composition of the catalyst is calculated by weight percentage: 30% CuO-31% ZnO% -28% Al 2 O 3 -5%MgO-6%MnOx) Examples 2-15 (corresponding to catalysts 2-15), the catalysts were prepared according to the steps in Exam...
