Description

A kind of high-efficiency and continuous carbon dioxide recycle material for trapping and preparation method
Technical field
The present invention relates to a kind of collecting carbonic anhydride material, be specifically related to a kind of high-efficiency and continuous carbon dioxide recycle trapping material Material and preparation method.
Background technology
Carbon dioxide is the predominant gas causing greenhouse effect, and too high gas concentration lwevel can cause the one of ecosystem The calamitous great change of series, it will serious threat human survival.It is a kind of control two by the collecting carbonic anhydride in air storage The effective ways of carbonoxide concentration.Alkaline solution such as sodium hydroxide solution be at present carbon dioxide is rapidly and efficiently trapped the most square Material the most efficiently, becomes sodium carbonate liquor after sodium hydroxide solution absorbing carbon dioxide.But sodium carbonate is converted into hydrogen-oxygen Changing sodium to need to introduce calcium hydroxide and through a series of high temperature, dry, calcining and other processes, therefore the recovery of sodium hydroxide is one The process of highly energy-consuming, and this removal process is along with a large amount of discharges of carbon dioxide, therefore uses sodium hydroxide to carry out air The circularly trapping of middle carbon dioxide is uneconomic, and efficiency is the lowest.
Nano-porous materials such as zeolite molecular sieve is also used as solid titanium dioxide due to the pore structure with prosperity Carbon adsorbent.But adsorbed the zeolite needs of carbon dioxide in high temperature environments could desorption carbon dioxide, therefore use Zeolite carries out the process that the circularly trapping of carbon dioxide is a highly energy-consuming, is unpractiaca.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, it is an object of the invention to provide a kind of high-efficiency and continuous titanium dioxide Carbon cycle material for trapping and preparation method, this material is the nano-porous materials being loaded with sodium carbonate, in actual use, it is only necessary to The humidity changing material local environment can realize absorption or the desorption of carbon dioxide, i.e. realizes dioxy by the change of humidity Change trapping and the regeneration of adsorbent of carbon.Can circulate down on this procedural theory always, thus can realize the efficient of carbon dioxide Circularly trapping continuously.Comparing traditional carbon dioxide absorber, it is low that this invention has preparation cost, and cyclic process power consumption is low, can The advantages such as regeneration.
In order to achieve the above object, the present invention adopts the following technical scheme that
A kind of high-efficiency and continuous carbon dioxide recycle material for trapping, the effective ingredient of described material for trapping is nano-porous materials And the sodium carbonate of load, it is various membranaceous that its outward appearance is the outward appearance of nano-porous materials selected or nano-porous materials is made Or block structure.
The preparation method of high-efficiency and continuous carbon dioxide recycle material for trapping described above, comprises the steps:
(1) a kind of aperture nano-porous materials less than 500nm is selected；
(2) above-mentioned nano-porous materials is immersed in the sodium carbonate liquor that concentration is 1mol/L 2～3 hours；
(3) nano-porous materials that above-mentioned soaking in sodium carbonate solution is crossed is carried out normal temperature drying process, i.e. available final Carbon dioxide recycle material for trapping.
Preferably, described nano-porous materials is zeolite molecular sieve, activated carbon or both combinations.
Compared to the prior art, the invention have the advantages that
(1) the flourishing pore structure of nano-porous materials and huge specific surface area, little trapping material are made full use of Material can realize the absorbability of superpower carbon dioxide.
(2) material for trapping can realize circular regeneration by changing humidity, and meanwhile, circulation absorption process is entered at normal temperatures OK, it is only necessary to change humidity, renovation process is simple and energy consumption is low to rely on solar energy to realize.
(3) material for trapping preparation method is simple, and the cost of material is low in preparation, is suitable for extensive preparation and application.
(4) material for trapping has high selectivity to carbon dioxide.
Accompanying drawing explanation
Fig. 1 is that the chemical reaction free energy occurred in the present invention is with moisture subnumber variation diagram.
Fig. 2 is to select 5A molecular sieve as the carbon dioxide recycle material for trapping outward appearance of nano-porous materials in the present invention Figure.
Fig. 3 be in the present invention carbon dioxide recycle material for trapping microstructure schematic diagram.
Fig. 4 is the carbon dioxide recycle absorption figure that in the present invention, material for trapping carries out that experimental test obtains.
Detailed description of the invention
Principle and detailed description of the invention to the present invention elaborate below in conjunction with the accompanying drawings:
The chemical reaction that the present invention utilizes is:
CO 3 - 2 + nH 2 O ⇔ HCO 3 - 1 + OH - 1 + ( n - 1 ) H 2 O
Above-mentioned reaction is a reversible reaction, and its free energy of reaction under the constraint of nano-pore changes as shown in Figure 1.Work as water When molecule is less, free energy of reaction is less than zero, and reaction forward is spontaneous to be carried out, and the hydroxyl of generation can be combined with carbon dioxide, Absorbing carbon dioxide.When hydrone is more, free energy of reaction is more than zero, reacts the most spontaneous carrying out, and hydroxyl reduces, dioxy Change carbon desorption.
Below with 5A zeolite molecular sieve as specific embodiment.Weigh the 5A zeolite molecular sieve of 5g, be soaked in the carbon of 1mol/L In acid sodium solution 2 hours, carbonate is made to enter in molecular sieve pores.Filter out solution afterwards and molecular sieve after soaking is carried out Normal temperature drying obtains being loaded with the zeolite molecular sieve of sodium carbonate.Soak, be dried after molecular sieve as shown in Figure 2.Through above-mentioned Molecular sieve after method processes i.e. can be used as carbon dioxide recycle material for trapping.Its microstructure schematic diagram is as it is shown on figure 3, carbon Acid group and hydrone are limited in nanoaperture.
Fig. 4 is that the carbon dioxide recycle material for trapping preparing said method carries out carbon dioxide desorption/adsorb survey again Test result figure.In figure, square data points is gas concentration lwevel, and triangular data points is relative humidity.By absorbing carbon dioxide Saturated material for trapping is placed in sealed environment, and the atmosphere in this environment is identical with air, simultaneously by humidity measurement instrument and dioxy Change concentration of carbon detector to be also positioned in this environment.Raising the humidity in environment, hydrone enters in the hole of material for trapping, with Moisture to increase, from aforementioned principles, back reaction is spontaneous to be carried out, and hydroxide ion reduces, and carbon dioxide desorption, in environment Gas concentration lwevel raises, until the complete desorption of carbon dioxide, i.e. material for trapping realize regeneration.Now reduce humidity, moisture Son departs from material for trapping, and positive reaction is spontaneous to be carried out, and hydroxide ion increases, and carbon dioxide is adsorbed, dense carbon dioxide in environment Degree reduces, and still can realize collecting carbonic anhydride, and amount of collected does not reduce after material for trapping regeneration is described.
Above-mentioned is only with 5A zeolite molecular sieve as specific embodiment, it should be pointed out that common for the art For technical staff, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improve and profit Decorations also should be protection scope of the present invention.
