Description
The application is 2010102617883 divides an application.
Technical field
It is fast to the present invention relates to a kind of product hydrogen speed, safe hydroboration produce hydrogen methods and portable hydrogen generator.
Background technology
Hydrogen is as clear energy sources, for example hydrogen can be in fuel cell controlled and oxygen reaction, produce electric energy and water, the fuel cell energy turnover ratio is up to 60-80%, be much higher than best oil engine (40%) now, hydrogen receives very big concern as a kind of novel energy.But hydrogen critical temperature low (32.79K) is difficult to liquefaction, and the density of liquefaction hydrogen also very low (0.07kg/l), thus hydrogen be difficult to store and transportation, need with various hydrogen storage materials storages it.
Hydrogen storage method commonly used has metal storage hydrogen and compound storage hydrogen, and their hydrogen storage ability is strong.For example Qingization Magnesium can store the hydrogen of 7.8% (mass percent, down together) quality, and can reuptake hydrogen after discharging, and is reusable.Yet the metal hydrogen storage and discharge is very difficult, needs several Baidu temperature, causes actual use to be difficult to.Also useful sorbing material storage hydrogen in addition, carbon nanomaterial for example, but the adsorption temp low (for example 130K) that they need.Another kind of hydrogen storage material is for example hydroborate of compound storage hydrogen, utilizes reaction releasing hydrogen gas such as storage hydrogen compound and water, and hydrogen release conditions ratio is easier to, simultaneity factor hydrogen-storage amount height.
Hydroborate (M(BH
4) n, M=Li, Na, K, Mg, Al etc.), representative sodium borohydride (NaBH especially
4), contain the hydrogen of 10.6wt%, can and water natural reaction (hydrolysis reaction) emit whole hydrogen: NaBH
4+ 2H
20=NaBO
2+ 4H
2, reaction can be emitted the hydrogen that accounts for the total amount 10.8% of reaction, is a kind of good compound hydrogen storage material.Preparing hydrogen by sodium borohydride hydrolysis, the hydrogen storage capability height, saturated aqueous solution can reach 35%, and hydrogen-storage amount is 7.4%; And produce the hydrogen purity height, the hydrogen that hydrolysis produces does not contain CO and other impurity, has only small amount of moisture, can not cause the poisoning of catalyst in the fuel cell; Reaction conditions is simple, and reaction is control relatively easily; Reaction can be carried out at low temperatures, need not provide extra energy; NaBH
4The aqueous solution has flame retardant resistance, and security is good; And can stable existence after adding stablizer in air, accumulating and use safety; The product NaBO that reaction generates
2Environmentally safe, and can be used as synthetic NaBH
4Raw material carries out recycling.Yet its shortcoming is: it is very big that hydrolysis reaction product hydrogen speed is influenced by temperature and pH, and in room temperature and pure water, reaction half-time is several hrs, and hydrolysis is very slow from hydrogen discharging speed, is difficult to satisfy instantaneous, atm number service requirements; Secondly, pure NaBH
4Reactant aqueous solution can not be controlled, and causes in needs hydrogen, and speed of response is too slow again, and does not want that with the hydrogen time, system is put hydrogen again naturally, and pure water solution can not be deposited the long period, thereby lacks actual application value.Though under acidic conditions, speed of response is very fast, and is wayward, poor stability.
People are in sodium borohydride aqueous solution for this reason, add NaOH as stablizer (10-20% NaBH for example
4, the NaOH of 5-10%), form NaBH
4-water-NaOH and catalyzer (Pt/C for example, NiCl
2Deng) system, this aqueous solution is when pH=14, and the transformation period is 430 days, can deposit the long period.When needs hydrogen, use catalyzer contact solution, releasing hydrogen gas.Yet its deficiency is: the hydrate NaBO of the high density boron-containing compound that reaction generates
2Can precipitate, lump, be attached to catalyst surface, make catalyst deactivation, and occluding device; It is proportional to produce hydrogen speed and catalyst levels, and high yield hydrogen speed needs relatively large catalyzer, has increased product hydrogen cost; Use catalyzer to need a lot of function uniies (as pump, flow, circulation etc.) simultaneously, high density NaOH tool highly corrosive in addition, poor stability causes and produces the hydrogen storage equipment relative complex, be difficult to miniaturization, therefore be difficult to accomplish drive large-scale hydrogen fuel cell with small-sized product hydrogen storage equipment; Besides, though have than the long half-lift, produce hydrogen but still can slowly discharge, long-term storage causes container inner pressure too high, has potential safety hazard, the aqueous solution still can not long-term storage thus; Catalyzer needs special preparation, and cost is higher, causes product hydrogen use cost to increase.
US Patent No. 7438732B2 discloses a kind of based on NaBH
4Produce the structure (fuel cartridges) of hydrogen storage equipment, wherein mention NaBH
4And solid acid (for example tartrate, citric acid, phenylformic acid, H
3BO
3) powder activator (activation agent) mixing, can produce hydrogen with the water reaction again.Though this patent is mentioned available H
3BO
3And NaBH
4Mix, add the water reaction then and produce hydrogen, but it thinks that reaction hydrogen producing speed is slower, is not a good system (week or relatively insoluble anhydrous acids such as boric acid when mixed with NaBH
4Produce hydrogen in the presence of water at a relatively low rate, thus are less preferable).Though this patent is advocated to make activator with solid organic acid, for example uses tartrate or phenylformic acid, our experiment shows, as organic solid acid (for example tartrate and citric acid) and NaBH
4Mix and the water reaction, because the reaction process very exothermic can make tartrate/citric acid oneself decompose, produce trace amounts of CO, and the fuel cell of CO is harmful to, can make the fuel-cell catalyst inactivation.
Secondly, existing installation is based on NaBH

4The contact of alkaline solution utilizes feedback constant hydrogen supply pressure of control automatically.Wherein do not relate to NaBO yet
2The problem of caking.US Patent No. 7438732B2 is based on two tank body (NaBH

4The reaction of/solid activating agent produces the device of hydrogen, equally along with reaction process, and the NaBO of generation
2Hydrate will condense into piece/layer and hinder and the water reaction, and this device is not mentioned agglomeration problems how to abolish resultant in water and the solid reactant reaction process yet.
Chinese patent CN101330152 fuel cell hydrogen-feeding system connects, places the container A of sodium borohydride solution by pipeline and place the container B of solid sodium borohydride or solid sodium borohydride and sodium hydroxide and hydrogen container and by-pass valve control are formed by two.This invention is to reclaim the water vapor that uses hydrogen and oxygen to generate, the amount that adds water that the minimizing system needs emphatically behind fuel cell reaction.
By last, no matter at NaBH
4-water-NaOH and catalyst system are still at NaBH
4/ solid activating agent adds in the water reaction system, the NaBO that reaction produces
2The agglomeration problems of hydrate is not resolved all the time.At NaBH

4/ solid activating agent adds in the water reaction system, if it is in addition not broken to produce the solid resultant that generates in the hydrogen process, it can generate big caking, stop water to contact with reactant, reaction is stopped, having only like this to add abundant water, after the caking dissolving, could continue reaction; Yet too much Shuitu so contacts with reactant, causes speed of response too fast, has the danger of blasting.More safety apparatus be must adopt for this reason, product hydrogen storage equipment miniaturization and safety are difficult to make.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of can not only long-term storage, and it is fast to produce hydrogen speed, the hydroboration produce hydrogen methods that controllability is good.
Another object of the present invention is to provide a kind of simple in structure, easy to use, the portable hydrogen generator that security is good.
The present invention's first purpose realizes that main the improvement is that powder hydroborate and powder boron-oxygen are mixed by a certain percentage, during use with water reaction releasing hydrogen gas, thereby overcome the deficiencies in the prior art, realization the object of the invention.Specifically, hydroboration produce hydrogen methods of the present invention comprises that producing the hydrogen hydroborate puts with the moisture opening, contacts product hydrogen with water; It is characterized in that producing the hydrogen hydroborate is hydroborate and boron-oxygen, according to the B atomic molar than the mixture that mixes for 1:4-0.5, when producing hydrogen and the water contact reacts.
The present invention is said: hydroborate, same prior art, for example M(BH
4) n, M=Li, Na, K, Mg, Al etc. are wherein especially with NaBH
4The most commonly used.
Boron-oxygen is boric acid (H
3BO
3) and various boric acid dehydration after product, metaboric acid for example, pyroboric acid and B
2O
3Deng, they all are solid.
Before the detailed description, make a presentation by basic function and the effect that can reach invention earlier, so that those skilled in the art have one clearly to understand to the art of this patent scheme.
The applicant tests discovery: the mixture of hydroborate and boron-oxygen very stable (for example hydroborate and boron-oxygen mixture, the B atomic molar compares 1:1, under isolated steam situation, differential scanning calorimeter (DSC) test result shows, this mixture is stable on 100 ℃ of temperature, show that fully its mixture has high security, not touching water does not react, so can store for a long time, when producing hydrogen, needs make mixture contact (mixture is added to the water, or water adds in the mixture) with water.And when the mixture of hydroborate and boron-oxygen with after water contacts, boron-oxygen and hydroborate begin water-soluble, the aqueous solution of boron-oxygen is acid, impels the quick hydrolysis of hydroborate, and heat is emitted in reaction simultaneously, heated system, make hydroborate and boron-oxygen water solubility increase, more be dissolved in the water, make that reaction is faster, emit more heat, speed of response has consumed reaction until water more and more sooner and has namely stopped (the heat effect self-feedback of very exothermic reaction).The general reactional equation of hydroborate and boron-oxygen and water: M(BH
4) n+X+H
20 → H
2+ resultant (X is boron-oxygen).The borohydride hydrolytic process is BH
4 -With H in the solution
+Reaction process is optimization under negative ions mol ratio 1:1 condition in theory, however since during hydrolysis reaction temperature increase, make water power from having produced more H
+Ion, product is weakly alkaline simultaneously, so the ratio of hydroborate and boron-oxygen boron atom in a suitable scope, is tested and determined to be preferably 1:4-0.5.Wherein, better hydroborate and the boron atom ratio in the boron-oxygen are 1:2-0.7.
Among the present invention: various boron-oxygens, result difference not quite can be employed in the experiment.Though boron-oxygen solvability at normal temperatures is little, (the NaBH for example because hydroborate
4) with water be very exothermic reaction, in real reaction, can be dissolved in very soon and generate boric acid in the water, thereby impel hydroborate (NaBH for example
4) hydrolysis fast response releasing hydrogen gas very.Use different boron-oxygens, under identical hydrogen burst size, varying in weight of solid mixture (mainly is that the different boron-oxygens that contain same mole boron atom vary in weight (for example with mole H of boron atom
3BO
3With B
2O
3Vary in weight), but with the hydroborate that contains same mole boron atom (NaBH for example
4) after the mixing, hydrogen output is the same), B wherein
2O
3And NaBH
4Solid mixture hydrogen content/mass ratio the highest, be preferably combination, in addition B
2O
3Generating boric acid with the water reaction is thermo-negative reaction, can offset a part of NaBH
4The heat that hydrolysis reaction produces is conducive to the heat dissipation design of equipment.Use hydroborate (NaBH for example
4) and boron-oxygen mixture and water reaction, another advantage is that product component is single, it all is the hydrate (for example sodium pyroborate hydrate) of all kinds of boric acid sodium salts, do not contain other impurity (for example NaOH), simple process can be worked as purifying worker raw material and sells, and perhaps is used as and produces hydroborate (NaBH for example
4) initial product.
Secondly hydroborate and solid boron-oxygen preferably all adopt powder separately, and powder particle are more little, mix more evenly, and, powder makes contact area become big, is conducive to improve speed of response.
Hydrogen is produced in the mixture hydrolysis, and same prior art both can be to make the water contact mixture, also can be to make mixture contact water, and by controlling both contact velocities and contact amount, hydrogen speed and hydrogen output are produced in control.Wherein better be to make water contact (adding) mixture, can avoid high density boron-oxygen solution viscosity to separate out greatly and blocking pipe and equipment.
The present invention's second purpose realizes, portable hydrogen generator, comprise that two are deposited the encloses container that produces hydrogen mixture and liquid (for example water or acid solution) respectively, and the valve keyholed back plate road that is interconnected, valve control fluid infusion and put hydrogen channel separately is characterized in that depositing producing and produces the mechanical agitation device that there is air bag the hydrogen mixture below and/or utilizes pressure variation to drive in the hydrogen mixture encloses container.When producing hydrogen mixture and water contact reacts product hydrogen, produce pressure change in the encloses container, make air bag (for example rubber ball) that creeping deformation or mechanical agitation device (physical construction of for example utilizing draught head to drive) generation stirring take place, they one are to cause to produce hydrogen mixture and constantly move, and are difficult to condense into piece when making it to react with water; The 2nd, even producing caking, reaction can obtain fragmentation immediately, avoid the accumulation sclerosis; The 3rd, produce the hydrogen mixture motion, both made reaction to carry through to the end fully, guarantee device safety again.
The mechanical agitation device that utilizes pressure variation (pressure reduction) to drive in apparatus of the present invention, be by the pressure variation actuation movement device that is used as power, it for example can be the airtight metal vessel of scalable (for example elasticity), this container is flexible automatically in its external pressure change procedure, or this airtight Expansion container connects a flexible physical construction up and down, or convert to and rotatablely move, drive several metal arm rotations, stir reactant simultaneously, concrete apparatus structure form can have multiple, after the technician understands this design, can also make multiple unsubstantiality and improve.
In addition, there are pressed gas or weight/pressure assembly in a kind of liquid storage encloses container liquid level top that is preferably, utilizes liquid level weight/pressure to drive liquid automatically and adds in the mixture.
Be easier automatic control, a kind of better is to make except arranging, putting the hydrogen valve, and all the other all adopt check valve, and its opening of valves direction is by the processing requirement setting.
Hydroboration produce hydrogen methods of the present invention, with respect to prior art, owing to adopt hydroborate and boron-oxygen to mix by a certain percentage as producing hydrogen reactant, than the single employing hydroborate of prior art, perhaps add the NaOH system, not only have whole advantages of borohydride hydrolytic hydrogen production, and overcome hydroborate strong base solution hydrolytic hydrogen production, and use the deficiency of catalyzer hydrogen manufacturing.The present invention produces hydrogen mixture and water reaction product hydrogen speed is very fast, and reaction can finish in 3-10 face second, can satisfy the instantaneous hydrogen requirement of using, the need that particularly suitable is emergent.Produce H-H reaction simultaneously and control easily, only need simple both contact velocities of control and contact amount (for example adding water speed and amount), can control and produce hydrogen speed and hydrogen output.Particularly the present invention produces under the hydrogen mixture normal temperature and pressure safety and stability and can not put hydrogen certainly, but thereby long-term storage and undergoing no deterioration, be a kind of safe, easy to use, it is fast to produce hydrogen, need not use the hydroboration produce hydrogen methods of catalyzer or highly basic.Hydroboration produce hydrogen methods of the present invention because not using any catalyzer, does not have the catalyst deactivation problem, does not use the corrosion of high density NaOH etc. yet, and reactant and reaction generate product and all environment do not polluted.The portable hydrogen generator of the present invention, produce the mechanical agitation device that hydrogen thing below increases air bag and/or utilizes pressure variation to drive owing to deposit, not only effectively eliminate reaction and produced product caking in the hydrogen, has high security, and many safety precaution parts have been omitted, equipment is very simple, can make the miniaturization hydrogen production bioreactor, carries, easy to use.In addition, stirring also helps and reacts completely thoroughly.Particularly utilize air bag according to gas pressure change wriggling in the container, stop solid block automatically and/or abolish to produce in the H-H reaction process to generate solid block, have more method, simple in structure, reliability is high.The chemical reaction of simplifying with the water contact reacts produces hydrogen, only need arrange and open and close valve and/or check valve, check valve particularly, it is moving directly to utilize pressure change to drive liquid, air-flow automatically, make that the control reaction process is simple, need not use any control panel can realize automatic control, also without any moving member, thereby can make the hydrogen generator portable, that hydrogen-storage density is high, be particularly suitable as the hydrogen source of movable type, small-sized and micro fuel cell (power is less than 300W).
