Embodiment 1
[0033] Add 1000mL of water into the dissolution tank, add 40g of nickel chloride and 34g of ammonium metatungstate to dissolve, and add the solubility to 10.9g / cm -3 495 milliliters of aluminum chloride solution, preparation acid working solution A, the pH value of solution A is 1.8, gets 160g ammonium bicarbonate and is made into the aqueous solution that molar concentration is 2.5mol / l. Add 350mL of water into the reaction tank, and the temperature rises to 70°C. Under the situation of stirring, solution A, ammonium bicarbonate aqueous solution, and concentration are 18% (weight) ammonia water and flow into the reaction tank in parallel to form a gel. The gelation temperature is 70° C., and the gelation time is 0.5 hour. The value is 8.5. Aging for 1 hour after gel forming. Then filter, add 600ml of clean water and 6.3g of molybdenum trioxide to the filter cake, beat and stir evenly, filter, dry the filter cake at 80°C for 5 hours, then extrude it, wash it with clean water...
Embodiment 2
[0035] According to the method of Example 1, according to the component content ratio of catalyst B in Table 1, add aluminum chloride, nickel chloride, ammonium metatungstate and zirconium oxychloride to prepare acidic working solution A in the dissolution tank, take 100g Ammonium bicarbonate is made into a solution with a molar concentration of 2.0 mol / l. Add 350mL of water into the reaction tank, and the temperature rises to 55°C. Under the situation of stirring, solution A, ammonium bicarbonate aqueous solution and concentration are 10% (weight) ammonia water and flow into the reaction tank to form gel, the gel forming temperature is 55 ℃, the gel forming time is 2 hours, the pH The value is 8.0. Aging for 2 hours after gel forming. Then filter, wash the filter cake twice with 500mL of clean water, add clean water and molybdenum trioxide, beat and stir evenly, filter, dry the filter cake at 70°C for 7 hours, then extrude it, wash it twice with clean water, wet the bar It...
Embodiment 3
[0037] According to the method of Example 1, according to the component content ratio of catalyst C in Table 1, nickel nitrate, phosphoric acid, aluminum nitrate, ammonium metatungstate are added to the dissolution tank to prepare acidic working solution A, and 120g of ammonium oxalate is taken to make mole A solution with a concentration of 1.8 mol / l. Add 350mL of water into the reaction tank, and the temperature rises to 60°C. In the case of stirring, solution A, ammonium oxalate aqueous solution and ammonia water with a concentration of 15% (weight) are added into the reaction tank to form gels. The gelation temperature is 60°C, and the gelation time is 2 hours. 8.5, then add molybdenum trioxide, beating and stirring evenly, filter, and dry the filter cake at 120°C for 1 hour, then extrude into a strip, dry the wet strip at 130°C for 3 hours, and roast at 600°C for 3 hours to obtain the final catalyst C. The composition and main properties are shown in Table 1, and the por...
