Embodiment 1
[0036] The preparation method of fine desulfurizer described in the present embodiment is:
[0037] (1) The three components of basic zinc carbonate, copper carbonate and alumina cement of the following parts by weight are mixed together and stirred uniformly:
[0038] Basic zinc carbonate, 65 parts;
[0039] Copper carbonate, 15 parts;
[0040] Bauxite cement, 10 parts;
[0041] (2) 2 parts by weight of water glass are dissolved in water to form a viscous solution, and stir evenly;
[0042] (3) uniformly mix the mixture obtained in the step (1) with the viscous solution of the binder obtained in the step (2), and extrude it into In the form of strips, it was cured at 30°C for 60 hours, sent to a drying oven, and baked at 110°C for 1 hour to make fine desulfurizer A. The desulfurizer has a sulfur capacity of 11.3% at 100°C and a sulfur capacity of 12.4% at 170°C.
Embodiment 2
[0044] (1) four components of the basic zinc carbonate, copper carbonate, iron oxyhydroxide and alumina cement of the following parts by weight are mixed together and stirred uniformly:
[0045] Basic zinc carbonate, 60 parts;
[0046] Copper carbonate, 15 parts;
[0047] r-iron oxyhydroxide, 3.5 parts;
[0048] Bauxite cement, 10 parts;
[0049] (2) 1.5 parts by weight of water glass is dissolved in water to form a viscous solution, and stir evenly;
[0050] (3) uniformly mix the mixture obtained in the step (1) with the viscous solution of the binder obtained in the step (2), and extrude it into In the form of strips, it was cured at 20°C for 36 hours, sent to a drying oven, and baked at 130°C for 3 hours to make fine desulfurizer B. The desulfurizer has a sulfur capacity of 12.8% at 100°C and a sulfur capacity of 13.3% at 170°C.
Embodiment 3
[0052] The preparation method of fine desulfurizer described in the present embodiment is:
[0053] (1) four components of the basic zinc carbonate, copper carbonate, iron oxyhydroxide and alumina cement of the following parts by weight are mixed together and stirred uniformly:
[0054] Basic zinc carbonate, 55 parts;
[0055] Copper carbonate, 20 parts;
[0056] r-iron oxyhydroxide, 5 parts;
[0057] Bauxite cement, 9.5 parts;
[0058] (2) 4 parts by weight of carboxymethylcellulose powder are dissolved in water to form a viscous solution, and stir evenly;
[0059] (3) uniformly mix the mixture obtained in the step (1) with the viscous solution of the binder obtained in the step (2), and extrude it into In the form of strips, it was cured at 40°C for 48 hours, sent to a drying oven, and baked at 120°C for 2 hours to make fine desulfurizer C. The desulfurizer has a sulfur capacity of 11.5% at 20°C and a sulfur capacity of 15.0% at 170°C.
