[0037] The preparation method of zinc oxide desulfurizer comprises the following sequence and steps:
[0038] a. Dissolve NaOH with 11.5%-13% deionized water to make NaOH aqueous solution;
[0039] b. Dissolve AlCl·6H with 11.5%-13% deionized water 2 O, make aluminum salt solution;
[0040] c. Under stirring, add the NaOH aqueous solution dropwise to the aluminum salt aqueous solution to make aluminum sol;
[0041] d. Add sodium-based bentonite to the aluminum sol, stir and beat to make a cross-linked bentonite slurry;
[0042] e. Methyl cellulose, aluminate cement, ZnO, ZnCO 3 、TiO 2 , NiO is added to the cross-linked bentonite slurry, mixed and rolled, and extruded into strips;
[0043] f. Dry at 80°C-120°C for 3h-5h; then roast at 350°C-400°C for 4h-5h to make a desulfurizer.
Embodiment 1
[0045] Take 225g of deionized water and dissolve 16g of NaOH to make NaOH aqueous solution. Take 225g of deionized water and dissolve 50g of AlCl 3 .6H 2 O, to make aluminum salt solution. Under stirring, NaOH aqueous solution was added dropwise to aluminum salt aqueous solution to make aluminum sol. Add 100g of sodium-based bentonite to the aluminum sol, stir and beat to make a cross-linked bentonite slurry. Add 30g methylcellulose, 100g aluminate cement, 400gZnO, 500gZnCO to the crosslinked bentonite slurry in turn 3 , 50gTiO 2 , 50g NiO, mixed and rolled, extruded into strips, dried at 80°C for 5 hours, and roasted at 350°C for 5 hours to make zinc oxide desulfurizer A. The main physical and chemical properties are shown in Table 1.
