Embodiment 1
[0022] Example 1: Fully wash the activated carbon particles with deionized water to remove impurities on the surface, and then fully soak them in deionized water for 6 hours to remove impurity ions adsorbed by activated carbon; ② Weigh the corresponding mass of activated carbon 0.5% The copper oxide was loaded on activated carbon by equal volume impregnation method; ③. Vacuum dried at 100°C for 4h; ④. Continued to vacuum dry at 120°C for 5h;
Embodiment 2
[0023] Example 2: Fully wash the activated carbon particles with deionized water to remove impurities on the surface, and then fully soak them in deionized water for 2 hours to remove impurity ions adsorbed by activated carbon; ② Weigh the corresponding mass of activated carbon 1% The copper oxide was loaded on activated carbon by equal volume impregnation method; ③. Vacuum dried at 100°C for 4h; ④. Continued to vacuum dry at 120°C for 5h;
Embodiment 3
[0024] Example 3: Fully wash the activated carbon particles with deionized water to remove impurities on the surface, and then fully soak them in deionized water for 4 hours to remove impurity ions adsorbed by activated carbon; ②Weigh the corresponding mass of activated carbon 5% Manganese oxide was loaded on activated carbon by equal volume impregnation method; ③. Vacuum dried at 85°C for 4h; ④. Continued to vacuum dry at 110°C for 8h.
[0025] see figure 1 , The device for implementing the method of the present invention includes two activated carbon adsorption beds with microwave generators, two sulfur absorption pools, connecting pipelines and several three-way valves. The activated carbon particles of the above-mentioned examples of supported catalysts were placed in each adsorption bed. A first microwave generator 10-1 is provided next to the first adsorption bed 9-1, and a first sulfur recovery tank 11-1 is attached; a second microwave generator 10-2 is arranged nex...
