Embodiment 1
[0029] 1. Preparation of Vector
[0030] Titrate the sodium silicate solution with 80--90ml of 18% hydrochloric acid solution. The sodium silicate solution is diluted with 200ml of 26% sodium silicate solution and 300ml of water. The titration temperature is normal temperature, the speed is 20ml / min, the titration end point is PH3--7, after titration, stand for 3 hours, filter, wash, dry, and get SiO after drying 2 , the SiO 2 Soak in 10% ammonium chloride solution for 4 hours, filter, wash, and dry at 120°C for 6 hours to obtain SiO 2 powder. SiO 2 Grind and sieve to get 40---300 mesh SiO 2 The carrier is spare.
[0031] 2. Catalyst preparation
[0032] Add 120g of cobalt nitrate and 30g of calcium nitrate to the beaker, add 160ml of water to dissolve, and take the SiO prepared by the above method 2 Carrier 40g and aluminum oxide monohydrate 9g, add carrier while stirring, adopt 20% anhydrous sodium carbonate solution to titrate (60g+190ml water), titration temperature...
