Example Embodiment
[0013] Example 1
[0014] The catalyst was prepared according to the following weight percentages: 5kg of ceria, 5kg of zirconia, 15kg of activator, 40kg of carbide slag, and 35kg of manganese ore waste slag, wherein the activator was molten salt furnace waste slag.
[0015] The above catalyst is added to industrial grade calcium hydroxide in a proportion of 1%. The calcium hydroxide mesh number is ~ 260, and the content is > 75%. The industrial application test of Henan Cement Co., Ltd., the industrial test shows that: under the same desulfurization emission control conditions Under the following conditions, by adding a catalyst, the amount of calcium hydroxide of the desulfurizing agent is reduced by 22%, and the catalyst shows a good reaction performance.
Example Embodiment
[0016] Embodiment 2
[0017] The catalyst was prepared according to the following weight percentages: 10 kg of ceria, 10 kg of zirconia, 15 kg of activator, 30 kg of carbide slag, and 35 kg of manganese ore waste residue.
[0018] The above catalyst is added to industrial grade calcium hydroxide according to the proportion of 10%. The calcium hydroxide mesh number is ~ 260 and the content is > 75%. The industrial application test of Henan Cement Co., Ltd. shows that: under the same desulfurization emission control conditions Under the following conditions, by adding a catalyst, the amount of calcium hydroxide of the desulfurizing agent is reduced by 32%, and the catalyst shows a good reaction performance.
Example Embodiment
[0019] Embodiment 3
[0020] The catalyst was prepared according to the following weight percentages: 6 kg of ceria, 12 kg of zirconia, 20 kg of activator, 40 kg of calcium carbide slag, and 22 kg of manganese ore waste residue.
[0021] The above catalyst is added to industrial grade calcium hydroxide according to the proportion of 10%. The calcium hydroxide mesh number is ~ 270, and the content is > 75%. The industrial application test of Henan Cement Co., Ltd., the industrial test shows that: under the same desulfurization emission control conditions Under the following conditions, by adding a catalyst, the amount of calcium hydroxide of the desulfurizing agent is reduced by 25%, and the catalyst shows a good reaction performance.
