Embodiment 1
[0029] The catalyst is prepared by the following steps:
[0030] (1) Activated carbon pretreatment: mix activated carbon with 5wt% nitric acid aqueous solution at a mass ratio of 1:3, stir evenly, treat at 60°C for 4h, wash with deionized water until neutral, and dry at 120°C for 5h to obtain Pretreated activated carbon.
[0031] (2) Preparation of catalyst precursor: add cobalt nitrate and yttrium nitrate to distilled water, stir and heat to 80°C, and after they are completely dissolved and cooled, a solution containing auxiliary components is obtained for use; In dilute hydrochloric acid with a fraction of 2%, a solution containing the active component is obtained. After mixing the solution containing the active component and the solution containing the auxiliary component, adjust the pH value of the solution to 6 with sodium carbonate to obtain a mixed solution. The pretreated activated carbon was added into the solution for equal volume impregnation for 3 hours, and after...
Embodiment 2
[0036] The catalyst is prepared by the following steps:
[0037] (1) Activated carbon pretreatment: mix activated carbon with 2wt% nitric acid aqueous solution at a mass ratio of 1:5, stir evenly, treat at 90°C for 2h, wash with deionized water until neutral, and dry at 100°C for 4h to obtain Pretreated activated carbon.
[0038] (2) Preparation of catalyst precursor: Silver nitrate and cerium nitrate are added to distilled water, stirred and heated to 90°C, and after they are completely dissolved and cooled, a solution containing auxiliary components is obtained for use; the active component palladium chloride Dissolve it in dilute hydrochloric acid with a mass fraction of 4% to obtain a solution containing the active component. After mixing the solution containing the active component and the solution containing the auxiliary component, adjust the pH value of the solution to 5 with sodium carbonate to obtain a mixed solution , add the pretreated activated carbon to the mixe...
