Embodiment 1
[0011] Weigh 100g Al 2 o 3 Small ball carrier, calcined at 500°C for 2h (at this time, the particle size is φ0.8-1.2, and the water absorption rate is ~0.8ml H 2 O / g Al 2 o 3 ). Measure RuCl 3 Solution (Ru concentration 5mg / ml in the solution, adopt RuCl 3 .3H 2 O configuration) 60ml is poured into the beaker, diluted to 66ml, while shaking, shaking, pour the solution into Al 2 o 3 in the ball. Wash the beaker wall with 6-10ml deionized water, pour Al 2 o 3 in the ball. Shake it well, dry it at 120°C for 2 hours, and bake it at 960°C for 3 hours, so that the weight composition is about 0.3% RuO 2 / Al 2 o 3 catalyst.
Embodiment 2
[0013] Weigh 7.6gCe(NO 3 ) 3 .6H 2 O, dissolved in 77ml deionized water, adjust the pH value of the solution to 7-8. Weigh 100g Al 2 o 3 Pour the small ball carrier (roasted, with the same physical properties as Example 1) into the previous solution, stir constantly, and shake well. Dry at 120°C for 2h, then bake at 500°C for 2h. Measure RuCl 3 Solution (solution concentration and configuration method are the same as Example 1) 60ml is poured in the beaker, dilutes to 66ml, stirs and shakes well, at the same time pours the solution into Al 2 o 3 in the ball. Wash the beaker wall with 6-10ml deionized water, pour Al 2 o 3 in the ball. Shake well and dry at 120°C for 2 hours, then bake at 960°C for 3 hours. Thus obtained a weight composition of approximately 0.3% RuO 2 / 3%CeO 2 / Al 2 o 3 catalyst.
Embodiment 3
[0015] Weigh 19.4g KNO 3 Dissolve in 230ml water, adjust the pH value of the solution to 7-8. Weigh 300gAl 2 o 3 Spheroid carrier (physical property is the same as example 1), adopts the same process of example 2 to make about 0.3% RuO by weight composition 2 / 3%K 2 O / Al 2 o 3 catalyst.
