Embodiment 1
[0027] 590 g of spent catalyst fine powder, 65 ml of water glass, and 15 g of sodium hydroxide were added to water and stirred evenly to form a slurry with a solid content of 35% by weight, which was spray-dried to form microspheres with a particle size of 0-150 μm; 300 g of microspheres were immersed in 300 ml of 15 wt% ammonium sulfate solution for 8 h, and then dried at 120 °C; the dried material was calcined at 600 °C for 1 h to obtain catalyst A.
Embodiment 2
[0029] 200 g of spent catalyst, 10 g of sodium cellulose, 8 g of sodium carbonate, 18 ml of water glass, and water were added, ground in a ball mill for 2 h, and pressed on a tablet machine; % by weight aluminum sulfate solution, impregnated for 2 h, and then dried at 100 °C; the dried material was calcined at 300 °C for 10 h to obtain catalyst B.
Embodiment 3
[0031] 350 g spent catalyst fine powder, 30 ml water glass, 10 g potassium hydroxide, 8 g polyacrylamide, add water, and extrude on the extruder; 150 g strip material is immersed in 170 ml, 15% by weight of ammonium sulfate The solution was immersed for 12 h, and then dried at 110 °C; the dried material was calcined at 450 °C for 5 h to obtain catalyst C.
