[0043] Example 1
[0044] Dissolve the nickel chloride and aluminum chloride solutions in purified water respectively, then add tetraethylammonium hydroxide and polyoxyethylene (20) sorbitan monooleate (Tween 80), mix well, and prepare mixed solution A , The weight concentration of NiO in mixed solution A is 19g / L, Al 2 O 3 The weight concentration is 13g / L, and the amount of organic compounds accounts for the amount of synthetic nickel and aluminum precipitates with NiO and Al 2 O 3 Based on the weight of 25.0wt%, tetraethylammonium hydroxide accounts for 55wt% of the mixed organic compound. Dissolve ammonium metatungstate, ammonium molybdate and aluminum chloride solutions in purified water respectively to prepare mixed solution B. WO in mixed solution B 3 The weight concentration is 39g / L, MoO 3 The weight concentration is 16g / L, Al 2 O 3 The weight concentration of 13g / L. Ammonia water with a concentration of 10% (weight) was added to solution A under stirring, the gel formi...

[0045] Example 2
[0046] According to the method of Example 1, according to the component content ratio of catalyst B in Table 1, add nickel nitrate, aluminum nitrate, and zirconium oxychloride solution to dissolving tank 1, and combine tetrabutylammonium hydroxide and stearic acid polyoxygen After the ethylene (12) grease is mixed, it is added to the solution tank 1. The amount of the mixed organic compound accounts for the synthesis of nickel and aluminum precipitates (NiO and Al 2 O 3 Calculated) 35wt% of the weight, tetrabutylammonium hydroxide accounts for 60wt% of the amount of the mixed organic compound, and the working solution A is prepared after stirring evenly. Add aluminum nitrate, ammonium metatungstate and ammonium molybdate to the dissolving tank 2 to prepare working solution B. Ammonia water with a concentration of 8% (weight) was added to solution A under stirring, the gel forming temperature was maintained at 55°C, the pH value was controlled at 8.0 at the end...

[0047] Example 3
[0048] According to the method of Example 1, according to the component content ratio of catalyst C in Table 1, add nickel chloride, aluminum chloride, and phosphoric acid solution into the dissolution tank 1, and combine the cetyltrimethylammonium bromide and After the isomeric deca alcohol polyoxyethylene (8) ether is mixed, it is added to the solution tank 1. The amount of mixed organic compound accounts for the weight of the synthesized nickel and aluminum precipitates (based on NiO and Al 2 O 3 Calcium) 40.0wt%, cetyltrimethylammonium bromide accounts for 42wt% of the mixed organic compound dosage. After stirring evenly, prepare working solution A, and add aluminum chloride, ammonium metatungstate and molybdenum to the dissolution tank 2. Prepare working solution B with ammonium acid. Ammonia water with a concentration of 8% (weight) was added to solution A under stirring, the gel forming temperature was maintained at 50°C, the pH value was controlled at ...
