Description
Technical field
The invention discloses a kind of method that desulphurization catalyst is prepared using peanut shell, belong to field of catalyst preparation.
Background technology
Desulfurization refers to remove harmful sulfidic material contained in industrial gasses, mainly hydrogen sulfide, in addition with curing
The organic sulfurs such as carbon, carbonyl sulfide, mercaptan, thioether.
Peanut is the main oil crops in China, and its total output and export volume occupy first place in the world, China's peanut gross annual output
Amount accounts for the 40% of Peanut total output, can about produce 5,000,000 tons of peanut shells every year up to 15,000,000 tons or so.The chemistry of peanut shell
Composition is relatively stable, and typical quality percentage composition is：Crude fibre 63.27%, lignin 34.21%, ash content 3.17%, contain
There are a small amount of starch, protein etc..Peanut shell porosity is big, structure is more loose, and density is small, and matter is crisp, and toughness is poor, uses vapor
The activated carbon of good adsorption performance is can obtain after activation, the content of peanut shell lignin is far above timber and wheat straw, at present peanut
Shell can be used for waste water treating agent, activated carbon, packaging material, animal feeding-stuff premix, edible mushroom or flowers culture medium, veterinary drug and add
Add agent carrier etc..
As people are to the pay attention to day by day of environmental protection, environmental regulation is also increasingly strict, and reduces the sulphur of gasoline and diesel oil
Content is considered as one of most important measure for improving air quality, because the sulphur in fuel can be to the property of vehicle catalytic converter
It can have adverse effect on, sulfur oxide present in automobile engine tail gas can suppress the noble metal catalyst in converter
And can be allowed to occur irreversibly to be poisoned, the gas discharged from poorly efficient or poisoning converter contains unburned non-methane hydrocarbon
With nitrogen oxides and carbon monoxide, through hydrophilic dye, these component reactions form ground level ozone, more often turn into " smog ".In addition,
According to the rules, the original discharge concentration of the sulfur dioxide in flue gas is less than 650mg/Nm3, and require in the flue gas after processing
Content of sulfur dioxide have to be lower than 110mg/Nm3, dust have to be lower than 50mg/Nm3。
At present, the method on reducing sulfur content mainly has spray drying process, flue gas circulating fluidized bed method and seawater to take off
Sulphur method, first spray drying process refer to that using lime as desulfurization absorbent lime is through digesting and adding water that calcium hydroxide breast, calcium hydroxide is made
The atomising device that breast is squeezed into absorption tower by pump, in absorption tower, the absorbent and flue gas that are atomized into fine drop mix
Splice grafting touches, with the SO in flue gas2Generation chemical reaction generation CaSO3, the SO in flue gas2It is removed, but this method desulfuration efficiency
Than relatively low, long-term use can cause the easy dust stratification of device, produce corrosion；The flue gas circulating fluidized bed method of next refer to agent prepare,
The parts such as absorption tower, Desulphurization recycling, deduster and control system form.The technique is typically made using the slaked lime powder of dry state
For absorbent, other dry powder for having absorbing reaction ability to sulfur dioxide or slurries can be also used as absorbent, but the party
Method requires high for lime quality and grain diameter, and operation is more complicated；Last seawater desulfurizing process is the alkali using seawater
Degree reaches a kind of sulfur method of removing sulfur dioxide in flue gas, but cost is higher during this method processing, in operating process
Pollution may be produced to environment.
The content of the invention
Present invention mainly solves technical problem：For Sulfur Dioxide On Human and environmental hazard in current vehicle exhaust
Greatly, although and traditional sulfur method can reduce sulfur content, desulfuration efficiency still be present than relatively low, running cost compared
It is higher, and in operating process the problem of meeting indirect pollution environment, there is provided it is a kind of to prepare desulphurization catalyst using peanut shell
Method, this method remove partial impurities, add sodium abietate, sodium chromate etc. pair first with soaking with sodium hydroxide peanut shell
Peanut shell is enlarged hole, and preliminary modified, and then it is carbonized, by the peanut shell after charing and blast furnace slag powder,
The materials such as sulfuric acid solution, nickel nitrate solution are mixed, and in-depth is modified, you can obtains desulphurization catalyst.The present invention is made
Desulphurization catalyst using peanut shell be raw material, realize twice laid, reduce operation cost, when in use, not only grasp
Make simple and easy, and be safe from harm in operating process for environment so that desulfurization degree reaches more than 88.5%.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
(1) take peanut shell to be cleaned with clear water, be put into container, add the hydroxide that mass fraction is 5~10% thereto

~0.3% sodium chromate and the methyl diethanolamine of sodium hydroxide solution volume 20~30%, 1~2h of agitating and heating, temperature
It is set as 80~90 DEG C, speed setting is 300~450r/min；
(2) after above-mentioned heating terminates, filter while hot, the peanut shell of gained is put into extruder extrude it is blocking, then
1~3h in retort is put it into, temperature is set as 700~800 DEG C, after charing terminates, charing block is cooled into room temperature, put
Enter in pulverizer, be ground into 90~110 mesh particles；
(3) particle of above-mentioned gained is put into container, then adds the zinc roasting of granular mass 10~15% thereto respectively
100~110 mesh blast furnace slag powders of sand and granular mass 10~15%, stir, then using 0.2~0.4mol/L sulphur
Acid solution immersion mixture, frequency is placed in as in the environment of 800~900MHz, 40~45min of agitating and heating, temperature is set as 65
~75 DEG C；
(4) after above-mentioned agitating and heating terminates, room temperature is cooled to, is filtered after standing 1~2h, the filtrate of gained is put into
In container, mass fraction is added thereto and is 50~55% soaking in sodium carbonate solution filtrate, then adds carbon thereto respectively
The mass fraction of acid sodium solution volume 10~15% be 3% nickel nitrate solution and sodium carbonate liquor volume 70~80% it is anhydrous
Ethanol, temperature are set as 55~60 DEG C, filtered after 2~3h of agitating and heating, collect filtrate；
(5) filtrate of above-mentioned gained is put into reactor, wherein air will be discharged using hydrogen, it is warming up to 300~
400 DEG C, after stirring 4~7h, hydrogen is discharged, is cooled to room temperature, collection filtrate, which is put into pulverizer, is ground into 100~110 mesh
Grain, you can obtain desulphurization catalyst.
The present invention application process be：5~10g desulphurization catalysts produced by the present invention are taken to be put into automobile exhaust pipe screen pack
In, start 15~25min of running car, detect the gas discharged in automobile exhaust pipe with detector afterwards, as a result show flue gas
Middle content of sulfur dioxide is from 120~130mg/Nm3It is reduced to 5~15mg/Nm3So that desulfurization degree has reached more than 88.5%.
The beneficial effects of the invention are as follows：
(1) desulphurization catalyst produced by the present invention is raw material using peanut shell, realizes twice laid, reduces operation
Cost；
(2) when in use, not only operation is simple for desulphurization catalyst produced by the present invention, and in operating process for
Environment is safe from harm so that desulfurization degree reaches more than 88.5%.
