Embodiment 1
[0034] Cu(NO 3 ) 2 ·3H 2 O, Zn(NO 3 ) 2 ·6H 2 O was dissolved in deionized water to form a mixed solution A, Cu 2+ The concentration is 2.8mol / L, Zn 2+ The concentration is 2.5mol / L. Cu(NO 3 ) 2 ·3H 2 O and AlCl 3 ·6H 2 O was dissolved in deionized water to form a mixed solution B, Cu 2+ Concentration is 1.8mol / L, Al 3+ The concentration is 2.0mol / L. Add deionized water in the reaction tank, sodium metaaluminate solution (containing Al 2 o 3 42g / L) and the mixed solution A were added into the reaction tank concurrently, the gelling temperature was 60°C, the gelling pH was 7.5, and the gelling time was 1.0 hour to obtain slurry I. The slurry I was aged under stirring, the stirring speed was 200 rpm, the aging temperature was 75° C., the pH value was 7.0, and the aging time was 0.7 hours. After aging, the mixed solution B and sodium carbonate solution are added to the aged slurry I in parallel, the molar ratio of the amount of sodium carbonate to the total amoun...
Embodiment 2
[0036] According to the method for embodiment 1, by the component content ratio of catalyst B in table 1, Cu(NO 3 ) 2 ·3H 2 O, Zn(NO 3 ) 2 ·6H 2 O was dissolved in deionized water to form a mixed solution A, and Cu(NO 3 ) 2 ·3H 2 O and Al(NO 3 ) 3 9H 2 O was dissolved in deionized water to form mixed solution B. Add deionized water in the reaction tank, sodium metaaluminate solution (containing Al 2 o 3 45g / L) and the mixed solution A were added into the reaction tank concurrently, the gelling temperature was 55°C, the gelling pH was 7.2, and the gelling time was 0.8 hours to obtain slurry I. The slurry I was aged under stirring, the stirring speed was 210 rpm, the aging temperature was 72° C., the aging pH value was 6.8, and the aging was 0.5 hours. After aging, the mixed solution B and sodium carbonate solution are added into the slurry I in parallel, the molar ratio of the amount of sodium carbonate to the total amount of copper and zinc is 2.4, the gelling tem...
Embodiment 3
[0038] According to the method for embodiment 1, by the component content ratio of catalyst C in table 1, Cu(NO 3 ) 2 ·3H 2 O, Zn(NO 3 ) 2 ·6H 2 O was dissolved in deionized water to form a mixed solution A, and Cu(NO 3 ) 2 ·3H 2 O and Al 2 (SO 4 ) 3 18H 2 O was dissolved in deionized water to form mixed solution B. Add deionized water in the reaction tank, sodium metaaluminate solution (containing Al 2 o 3 52g / L) and mixed solution A were added into the reaction tank in parallel, the gelation temperature was 45°C, the pH value was 7.8, and the gelation time was 1.2 hours to obtain slurry I. The slurry I was aged under stirring, the stirring speed was 230 rpm, the aging temperature was 73° C., the aging pH value was 7.1, and the aging time was 0.6 hours. After the aging is finished, the mixed solution B and the sodium carbonate solution are added into the slurry I in parallel, the molar ratio of the amount of sodium carbonate to the total amount of copper and zin...
