Embodiment 1
[0028] Take by weighing 0.2093g ruthenium trichloride, 0.2330g zirconium chloride, 0.3506g tin tetrachloride, be dissolved in the solution of 3ml ethanol and water respectively, wherein the ratio of ethanol and water is 1: 1, after fully dissolving, above-mentioned three Mix the two solutions, add 6.978 g of carrier mesoporous silica, and impregnate with stirring at room temperature for 12 hours. Afterwards, it was dried in an oven at 80°C for 12 hours, and finally fired in a muffle furnace at 400°C for 4 hours. Catalyst A is obtained.
Embodiment 2
[0030] Take by weighing 0.2093g ruthenium trichloride, 0.2330g zirconium chloride, 0.3506g tin tetrachloride, be dissolved in the solution of 3ml ethanol and water respectively, wherein the ratio of ethanol and water is 1: 1, after fully dissolving, above-mentioned three Mix the two solutions, add 5g α-Al 2 o 3 Carrier, impregnated with stirring at room temperature for 12 hours. Afterwards, it was dried in an oven at 80°C for 12 hours, and finally fired in a muffle furnace at 400°C for 4 hours. Catalyst B is obtained.
Embodiment 3
[0032] Take by weighing 0.2093g ruthenium trichloride, 0.2330g zirconium chloride, 0.3506g tin tetrachloride, be dissolved in the solution of 3ml ethanol and water respectively, wherein the ratio of ethanol and water is 4: 1, after fully dissolving, above-mentioned three Mix the two solutions, add 6.978 g of carrier mesoporous silica, and impregnate with stirring at room temperature for 12 hours. Afterwards, it was dried in an oven at 80°C for 12 hours, and finally fired in a muffle furnace at 400°C for 4 hours. Catalyst C is obtained.
