Description
Technical field
The present invention relates to purifying formaldehyde Material Field, specially a kind of high pressure water heat load method prepares purifying formaldehyde material
Method.
Background technique
Formaldehyde has become one of indoor major pollutants because source is wide, toxicity is big, the pollution time is long etc., and formaldehyde is to human body
Harm depends on its concentration, stimulates eye mucous membrane at low concentrations, the upper respiratory tract is stimulated when concentration is slightly higher, causes cough, uncomfortable in chest, head
Pain and nausea cause rhinitis, pharyngitis, pulmonary emphysema, lung cancer when concentration is higher, or even dead.Oneself is through by the World Health Organization at present
It is determined as carcinogenic and causes deformed material.The public is had become by the indoor environmental pollution bring health problem that formaldehyde causes to look steadily
The new hot spot of purpose.
The method for being conventionally used to purifying indoor formaldehyde mainly has adsorption technology, photocatalysis technology, lower temperature plasma technology
And catalytic oxidation technologies.The technology being widely used at present is adsorbed using the high-ratio surfaces such as active carbon and molecular sieve material
Formaldehyde, to achieve the purpose that purify air, but due to the limited sorption capacity of such material, and normal temperature condition is easy to desorption
Defect brings very big obstacle to application.Common solution is to be modified processing to active carbon to pass through supported active
The mode of component (reactive component) improves the reactivity and sorptive power of active carbon PARA FORMALDEHYDE PRILLS(91,95), realizes efficient, permanent, quickly net
Change the purpose of formaldehyde.
Infusion process is that solid catalyst prepares a kind of widely applied method, activated carbon supported active component, with active carbon
For carrier framework, active component, which is scattered in solvent, is configured to maceration extract, and active carbon is sufficiently impregnated soaking, and moisture is steamed in drying
Hair evolution, active component deposition is retained in active carbon duct, the basic principle is that utilizing the surface tension and load at two interfaces
Adsorption capacity of the body to dip composition.To increase impregnation increment or impregnating depth, it will usually be optimized to immersion condition, such as in advance
First vacuumize, improve maceration extract temperature, increase stirring etc., there are still active component dispersibilities poor, component reunion, effecting reaction
The problems such as space is small, poor activity.
Summary of the invention
It is an object of the present invention to provide the technique optimization methods that a kind of infusion process prepares formaldehyde charcoal, using high pressure water heat load side
Method improves the removal ability and purification rate of impregnated carbon PARA FORMALDEHYDE PRILLS(91,95).
The present invention is achieved by the following technical scheme:
A kind of high pressure water heat load method prepares purifying formaldehyde MATERIALS METHODS, using the coaly activated carbon that CTC adsorbate is 100% as load
Body, organic amine are bis- (2- ethoxy) amino (trihydroxy methyl) methane (molecular formula C8H19NO5) it is used as active component, water is molten
Agent, ptfe autoclave are steeper.
Specifically, weighing certain carbon content active is placed in reaction kettle, a certain amount of certain density maceration extract is prepared, reaction is poured into
Stirring, makes active carbon be sufficiently impregnated soaking in kettle.Reaction kettle is covered, additional stainless cylinder of steel sealing fastening is placed in 165 in baking oven
DEG C constant temperature places 10h, takes out, Temperature fall, after sample in reaction kettle is dry at 80 DEG C, until moisture all volatilization evolutions,
It is to be measured that sample bottle is packed into after cooling.When implementation, every 50g active carbon is impregnated with the maceration extract that 100mL concentration is 0.036g/mL.
The present invention is prepared as background with purifying formaldehyde charcoal, provides a kind of impregnation technology optimisation technique, negative using high pressure hydro-thermal
On the one hand load technology improves maceration extract temperature, increases the diffusion velocity of active component, on the other hand by the pressure of steam generation
Power provides additionaling power to active component, pushes diffusion of the active component to inner surface of the carrier, the results showed that, using high pressure water
Heat load technology, under the conditions of identical impregnation increment, the net magnificent enhancing efficiency for preparing material PARA FORMALDEHYDE PRILLS(91,95) is very big, this sufficiently shows to adopt
Dispersion degree and the reactivity site that active component can be improved with the technology, increase the activated centre of carrier surface.
The present invention has rational design, provides the process modification optimization method that a kind of infusion process prepares solid catalyst, uses
High pressure water heat load method carries out the preparation of solid catalyst, and active component can be promoted in the diffusion velocity of carrier surface, improved
The dispersion degree of active component and the reactivity of catalyst.
Specific embodiment
Specific embodiments of the present invention are described in detail below.
Embodiment 1
Active carbon 50g, impregnation concentration 0.036g/mL(are prepared with bis- (2- ethoxy) amino (trihydroxy methyl) methane to be impregnated
Liquid), dosage 100mL pours into maceration extract in the ptfe autoclave for filling active carbon, and stirring is sufficiently soaked, will be reacted
Kettle covers, and additional stainless cylinder of steel sealing fastening is placed in 165 DEG C of constant temperature 10h in baking oven, takes out sample after cooling, does at 80 DEG C
It is dry that moisture, all volatilization is escaped.
Comparative example 1
Active carbon 50g, impregnation concentration 0.036g/mL, dosage 55mL pour into maceration extract in the beaker for filling active carbon, stir
It mixes, sealing and standing 3h in plastic packaging bag, dry, the evolution until moisture all volatilizees at 80 DEG C is sufficiently put into after wetting.
Comparative example 2
Maceration extract is heated to 60 DEG C and pours into again to fill active carbon by active carbon 50g, impregnation concentration 0.036g/mL, dosage 55mL
Beaker in, stirring is sufficiently put into sealing and standing 3h in plastic packaging bag after wetting, dry at 80 DEG C, until moisture all volatilization evolutions.
The above sample carries out purifying formaldehyde performance evaluation, and test condition see the table below:
Test result see the table below, and purification efficiency is characterized with attenuation constant k, and k value is bigger, and purification efficiency is higher, be to survey below
Try the calculated result of 60min:
As seen from the above table, the preparation method provided using the invention, in identical impregnation increment and later period to the drying process item of sample
Under part, the removal efficiency and removal rate for preparing material PARA FORMALDEHYDE PRILLS(91,95) are all improved to some extent.
The dispersion degree of active component can be improved under the premise of keeping identical activity component impregnation amount in the present invention program,
Increase the active interface and active site reacted with formaldehyde.Identical removal formaldehyde efficiency is such as kept, is provided using the invention
Method can reduce the dosage of active component to a certain extent, reduce production cost.
It should be pointed out that for the those skilled in the art of the art, without departing from the principle of the present invention,
Several improvement and application can also be made, these are improved and application is also considered as protection scope of the present invention.
