Embodiment 1
[0029] Take RuCl with a Ru content of 0.06g 3 ·3H 2 O solution, add deionized water to dilute to 50ml homogeneous solution, stir evenly, add 1.94g rutile type TiO to this solution 2 The carrier formed a homogeneous mixture; the mixture was heated and stirred at 60° C. until the solvent evaporated to dryness, and the obtained solid was dried in an oven at 110° C. for 12 h, and then calcined in a muffle furnace at 300° C. in an air atmosphere for 3 h. Calcined Ru / TiO 2 The catalyst was redispersed in 200ml, 1mol / L dilute ammonia water, stirred at room temperature for 12h; filtered, washed with dilute ammonia water, and then deionized water until the pH of the filtrate was 7; the filtered solid was dried in an oven at 80°C for 12h, That is, a catalyst for removing chlorine is obtained. Catalyst for dechlorination in H 2 Reduction treatment at 400°C for 3 hours in the atmosphere can obtain Ru / TiO 2 -400 Catalyst.

[0031] Take RuCl with a Ru content of 0.06g 3 ·3H 2 O solution, add deionized water to dilute to 50ml homogeneous solution, stir evenly, add 1.94g rutile type TiO to this solution 2 The carrier formed a homogeneous mixture; the mixture was heated and stirred at 60° C. until the solvent evaporated to dryness, and the obtained solid was dried in an oven at 110° C. for 12 h, and then calcined in a muffle furnace at 300° C. in an air atmosphere for 3 h. Calcined Ru / TiO 2 The catalyst was redispersed in 200ml, 1mol / L dilute ammonia water, stirred at room temperature for 12h; filtered, washed with dilute ammonia water, and then deionized water until the pH of the filtrate was 7; the filtered solid was dried in an oven at 80°C for 12h, That is, a catalyst for removing chlorine is obtained. Catalyst for dechlorination in H 2 Reduction treatment at 450°C for 3 hours in the atmosphere can obtain Ru / TiO 2 -450 Catalyst.
Embodiment 3
[0033] Take RuCl with a Ru content of 0.06g 3 ·3H 2 O solution, add deionized water to dilute to 50ml homogeneous solution, stir evenly, add 1.94g rutile type TiO to this solution 2 The carrier formed a homogeneous mixture; the mixture was heated and stirred at 60° C. until the solvent evaporated to dryness, and the obtained solid was dried in an oven at 110° C. for 12 h, and then calcined in a muffle furnace at 300° C. in an air atmosphere for 3 h. Calcined Ru / TiO 2 The catalyst was redispersed in 200ml, 1mol / L dilute ammonia water, stirred at room temperature for 12h; filtered, washed with dilute ammonia water, and then deionized water until the pH of the filtrate was 7; the filtered solid was dried in an oven at 80°C for 12h, That is, a catalyst for removing chlorine is obtained. Catalyst for dechlorination in H 2 Reduction treatment at 500°C for 3 hours in the atmosphere can obtain Ru / TiO 2 -500 catalyst.
