[0051] [Example 1]
[0052] Catalyst preparation:
[0053] step 1)
[0054] Prepare 0.3mol / l TiOSO 4 2000ml of aqueous solution, add 12g of activated carbon powder, drop 0.6mol / l ammonia water into this turbid solution to co-precipitate to form a gel substance, filter, wash, dry, and bake at 300°C for 2 hours in a nitrogen atmosphere to obtain a composite carrier core pink;
[0055] step 2)
[0056] Mix 45g of composite carrier core powder, 0.1g of n-butylamine and 0.1g of oxalic acid, and after kneading, extruding, pelletizing, and drying, the core of the composite carrier is prepared; 50g of titanium dioxide sol with a weight content of 10% is sprayed on On the core of the composite carrier, after drying, calcination at 850°C for 4 hours to make a composite carrier;
[0057] step 3)
[0058] 50 g of the composite support was immersed in a salt solution containing 0.50 g of Ru. Impregnated at room temperature for 6 hours, dried, and calcined at 480 °C for 2.5 hours to ...

[0062] Catalyst preparation:
[0063] step 1)
[0064] Prepare 0.3mol / l TiOSO 4 2000ml of aqueous solution, drop 0.6mol / l ammonia water into this turbid solution to co-precipitate to form a gel substance, filter, wash, dry, and roast in a nitrogen atmosphere at 300°C for 2 hours to obtain titanium dioxide powder;
[0065] step 2)
[0066] Mix 41g of titanium dioxide powder, 9g of activated carbon powder, 0.1g of n-butylamine and 0.1g of oxalic acid, and after kneading, extruding, pelletizing and drying processes, calcined at 850°C for 4 hours to prepare a composite carrier;
[0067] step 3)
[0068] 50 g of the composite support was immersed in a salt solution containing 0.50 g of Ru. Impregnated at room temperature for 6 hours, dried, and calcined at 480 °C for 2.5 hours to obtain a catalyst precursor; the catalyst precursor was reduced with hydrogen at 400 °C for 3 hours to obtain a finished catalyst;

Example Embodiment
[0071] [Example 3]
[0072] step 1)
[0073] Mix 9 g of the composite carrier core powder described in step 1) of Example 1, 0.02 g of n-butylamine and 0.02 g of oxalic acid, and after kneading, extruding, pelletizing and drying, calcined at 300°C for 2 hours in a nitrogen atmosphere , the core of the composite carrier is prepared;
[0074] step 2)
[0075] 410g of titanium dioxide sol with a weight content of 10% was sprayed on the core of 9g of composite carrier for several times, and after drying, calcined at 850° C. for 4 hours to prepare a composite carrier;
[0076] step 3)
[0077] 50 g of the composite support was immersed in a salt solution containing 0.50 g of Ru. Impregnated at room temperature for 6 hours, dried, and calcined at 480 °C for 2.5 hours to obtain a catalyst precursor; the catalyst precursor was reduced with hydrogen at 400 °C for 3 hours to obtain a finished catalyst;
[0078] Catalyst evaluation:
[0079] The catalyst prepared above is loaded in...
