Abstract
The present invention relates to a normal temp. iron oxide refined desulfurizing agent, and its composition includes: (1) main catalyst iron oxide zynthesis; a. ferrous sulfate 100 (by 100 portions of mass); b. precipitant; ammonia water less than 60, lime less than 60 and sodium carbonate less than 10. (2) adjuvant: nickel or chromium or copper or cadmium or other transition metals oxide (or oxide hydrate) less than 5; and (3). addesive and carrier; cement 30-50 and wood dust 5-10. Said invention product possesses high desulfurizing activity, strength and water-proof property.
Description
The present invention relates to a kind of gas purification catalyst, be specifically related to the improvement of ferric oxide desulfurizer.
Ferric oxide desulfurizer is a kind of desulphurization catalyst that is widely used in unstripped gas such as chemical fertilizer, organic synthesis, Coal Chemical Industry, petrochemical industry.But there is following weakness usually in conventional oxidation iron desulfurizing agent: (1) is desulphurizing activated low, generally penetrates Sulfur capacity less than 10% (outlet hydrogen sulfide is less than 0.03ppm, down together); (2) intensity is low, and the particle anti-crushing power is less than 35N/cm; (3) poor water resistance, water boil efflorescence in 2 hours is serious; (4) all there is the waste water and gas of contaminated environment to produce in the production process.
The purpose of this invention is to provide prevailing cheap chemical materials of a kind of employing and industrial waste is raw material, only needs to add an a little auxiliary and just can produce, and can increase substantially the normal temperature iron oxide desulfurizing agent of desulphurizing activated, intensity and resistance to water.
Normal temperature iron oxide desulfurizing agent of the present invention, its component is:
1. the major catalyst iron oxide is synthetic: a. ferrous sulfate 100 (following prescription is 100 parts of calculating with primary raw material ferrous sulfate quality all): the industry byproduct or the three wastes reclaim product.B. precipitating reagent: ammoniacal liquor is less than 60, and lime is less than 60, and sodium carbonate is less than 10 (being technical grade product)
2. auxiliary agent: nickel or chromium or copper or cadmium or other oxidation of interim metal (or oxide hydrate) are less than 5.
3. adhesive and carrier: cement 30～50 (Portland cement), wood chip 5～10 (woodworking mill's discarded object).
Normal temperature iron oxide desulfurizing agent method of manufacturing technology of the present invention is: earlier ferrous sulfate and precipitating reagent chemical combination are made iron oxide, add auxiliary agent, adhesive and carrier then and mix, extrusion, drying, roasting promptly get product again.
The iron oxide fine desulfurizer technical indicator that adopts above-mentioned formula range to make can reach (1) and penetrate Sulfur capacity 15%～20%; (2) intensity is greater than 50N/cm; (3) water-tolerant, water boil not efflorescence in 2 hours; (4) " environmental friendliness " is produced to select for use proper formulation can realize not having the three wastes.Enumerate two formulation examples below.
Embodiment 1.
Prescription: ferrous sulfate 100, ammoniacal liquor 36, lime 8, cupric oxide 4.5, cement 40, wood chip 10.Earlier with the ferrous sulfate dissolving, under agitation add ammoniacal liquor, lime, filtering-depositing, washing add cement, wood chip, cupric oxide, lime and fully mix in precipitation, compound extrusion, oven dry back roasting are promptly got product.
Embodiment 2.
Prescription: ferrous sulfate 100, lime 50, sodium carbonate 10, nickel oxide 4, cement 42, wood chip 10.Earlier with the ferrous sulfate dissolving, under agitation add lime, sodium carbonate, filtering-depositing, washing add cement, wood chip, nickel oxide and fully mix in precipitation, compound extrusion, oven dry back roasting are promptly got product
Each formula technique performance
Penetrate Sulfur capacity intensity resistance to water remarks
(%) (N/cm) (water boil 2 hours) prescription 1. 16.2 58.6 not efflorescence prescription 2. 18.9 73.7 not efflorescence of high quality and at a reasonable price are low in the pollution of the environment
Claims (1)
1, a kind of normal temperature iron oxide fine desulfurizer is characterized in that its component is: (1) major catalyst iron oxide synthetic:
A. ferrous sulfate 100 (following prescription is 10 parts of calculating with primary raw material ferrous sulfate quality all): the industry byproduct or the three wastes reclaim product.
B. precipitating reagent: ammoniacal liquor is less than 60, and lime is less than 60, and sodium carbonate is less than 10: be technical grade product.
(2) auxiliary agent: nickel or chromium or copper or cadmium or other oxidation of interim metal (or oxide hydrate) are less than 5.
(3) adhesive and carrier: cement 30～50 (common carbonate cement), wood chip 5～10 (woodworking mill's discarded object).
