Description
Technical field
The invention belongs to impregnated carbon technical field, have for a kind of sorbing material protecting function admirable and preparation method thereof.
Background technology
At present, domestic general deodorizing sorbing material is mainly prepared by carrier with coal mass active carbon, but this take coal as sorbing material prepared by raw material, not only guard time is not high, and ash content is high, and loading density is uneven, and loading density is large, cause filling tank or filter weight greatly, volume is large, and particularly when limited space, shortcoming is more obvious.
Compare traditional active carbon, asphalt-base spherical activated carbon has the series of advantages such as good sphericity, loading density is even, specific area is comparatively large, intensity is high, wear-resistant, corrosion-resistant.What particularly use in militay space flight deodorizing tank now is exactly be sorbing material prepared by carrier with asphalt-base spherical activated carbon, improves a lot before comparing.But because the preparation technology of original asphalt-base spherical activated carbon goes wrong, cause the spherical activated charcoal hydraulic performance decline of production, so cause sorbing material obtain barrier propterty can not meet new demand under performance indications.Therefore, be necessary to research and develop a kind of sorbing material that can meet performance indications under new demand.
Summary of the invention
The object of the present invention is to provide a kind of deodorizing sorbing material and preparation method thereof, be mainly used in the effective protection to materials such as ammonia, hydrogen sulfide, methyl mercaptan, methylamines.The absorbent charcoal carrier selected is asphalt-base spherical activated carbon, it supports active component Cu, K.
The present invention adopts following technical scheme to realize:
A kind of deodorization sorbing material, adopt asphalt-base spherical activated carbon as carrier framework material, on it, load has 5.1 ~ 10.2%(weight) Cu, 1.6 ~ 5.2%(weight) K, surplus is active carbon.
Wherein, in the weight of carrier active carbon for 100%.Such as carrier active carbon weight is 100g, then supported copper 5.1 ~ 10.2g, potassium 1.6 ~ 5.2g, so needs active component copper sulphate 12.8 ~ 25.6g(and cupric sulfate pentahydrate 20 ~ 40g), potassium chloride 3 ~ 10g.
The preparation technology of above-mentioned deodorization sorbing material mainly comprises active component and supports and activate two steps.
1, solution preparation
The active component of catalyst is mainly cupric sulfate pentahydrate and potassium chloride, in solution preparation process, above-mentioned active component is joined successively (distilled water consumption calculates by the water capacity of carrier) in a certain amount of distilled water, ensure that each active component is fully dissolved, solution temperature is generally at 60 ~ 80 DEG C.
2, flood
Adopt equivalent impregnation method, the mixed solution prepared is joined in load weighted asphalt-base spherical activated carbon, constantly stirs, maceration extract is fully contacted with asphalt-base spherical activated carbon, ensure that dipping evenly, fully, then sealing and standing 1 ~ 2h.
3, calcine
Calcining is the process of giving the certain catalytic reaction activity of impregnated carbon, is critical process prepared by sorbing material.Temperature controls between 140 ~ 160 DEG C, and the duration is greater than 4h.
A certain amount of Cu and active component auxiliary agent are added in distilled water, prepares sorbing material according to above-mentioned technique.The sorbing material the performance test results of preparation sees the following form:
As seen from the above table, sorbing material provided by the invention is compared the barrier propterty of QZ09-4, MH-97-1 sorbing material to ammonia, hydrogen sulfide and is improved.
The blending constituent comprising Cu and K is impregnated on carrier framework material by the present invention, is converted into the active component with reactivity by heat-activated, and cupric impregnating agent, to alkaline toxic and harmful (as ammonia), chemisorption reaction occurs; Containing potassium impregnating agent, there is the elimination ability to acid toxic and harmful (as hydrogen sulfide).
Compared with prior art, its advantage is as follows:
1, comparatively large, the pore structure of specific area distributes rational absorbent charcoal carrier;
2, the kind of load active component, mainly includes Cu and active component auxiliary agent, but is not limited to add other component on this basis;
3, on described carrier material, load specified activity component prepares sorbing material, has the effective protective capacities to ammonia, hydrogen sulfide.
The present invention is reasonable in design, utilize asphalt-base spherical activated carbon as carrier material, adopt equivalent impregnation method, supported and activating process by active component, complete asphalt-base spherical activated carbon load active component Cu and K, realize the effective protection to materials such as ammonia, hydrogen sulfide, methyl mercaptan, methylamines.Simultaneously because the loading density of sorbing material is little, load the advantages such as even, during for loading protective equipment, can reduce weight, reduced volume, the design and the production that can be Chemical Agent Resistant Material provide certain convenience.
Preparation technology of the present invention is simple, easy to operate, can realize mass production capabilities, for protective equipment designs, produces and provide convenience, can be used as the core scavenging material of future submarine atmospheric environment control system, Shenzhou spacecraft space flight deodorizing tank.
