Embodiment 1
[0022] Preparation of organic montmorillonite by ion exchange reaction. First, in 1000 mL of 80 °C deionized water, 1 mole of octadecylamine was acidified with equimolar concentrated hydrochloric acid, then injected into 1500 mL of montmorillonite dispersion, and continued to mix mechanically for 30 minutes. The obtained white precipitate was filtered and washed with 80 °C Washed with deionized water for 3 times, then air-dried naturally, and pulverized the organic montmorillonite with a pulverizer; finally, dried in a vacuum oven at 60°C for 24 hours.
[0023] With the alumina-silicon oxide hybrid with a particle size of 10 microns as the carrier, the nickel nitrate aqueous solution and the alumina-silicon dioxide hybrid were mixed at 40 °C in a weight ratio of 40 nickel: 60 alumina-silicon hybrid Mix under stirring for 1 hour. The obtained product was put into a muffle furnace and dried at 100° C. for 8 hours. Then calcined at 400°C for 3 hours, and finally used argon cont...

First, in 1000mL 80°C deionized water, 1 mole of octadecylamine was acidified with equimolar concentrated hydrochloric acid, then injected into 2000mL montmorillonite dispersion, and continued to mix mechanically for 30 minutes, the obtained white precipitate was filtered and washed with 80°C Washed with deionized water for 3 times, then air-dried naturally, and pulverized the organic montmorillonite with a pulverizer; finally, dried in a vacuum oven at 60°C for 24 hours.
[0035]With the alumina-silicon oxide hybrid with a particle size of 30 microns as the carrier, the aqueous solution of nickel nitrate and the hybrid of alumina-silicon dioxide were mixed at 60 °C in a weight ratio of 45 nickel: 55 of the alumina-silicon oxide hybrid Mix under stirring for 0.5 hours. The obtained product was put into a muffle furnace and dried at 80° C. for 12 hours. Then calcined at 450°C for 2 hours, and finally used...
