Circulate under a kind of Li-N-H of realization system microwave and put the method for hydrogen fast
Technical field
The present invention relates to hydrogen storage material technical field, particularly relate to a kind of realize coordinate hydride hydrogen-storing material microwave under put the method for hydrogen fast.The invention belongs to hydrogen storage material preparation technology and applied technical field.
Background technology
Along with being on the rise of environmental pollution and petering out of fossil energy, development new forms of energy become the urgent demand in countries in the world.Clean as one, the free of contamination green energy resource of Hydrogen Energy, causes the great interest of people.The applicable key issue of restriction hydrogen is safe and reliable hydrogen storage technology.Hydrogen storage technology is mainly divided into gaseous state to store up hydrogen, liquid storage hydrogen and solid-state storage hydrogen.Solid-state storage hydrogen because of its security and hydrogen-storage density high and studied widely.In solid-state hydrogen storage material, metal nitrogen base hydride is advantages such as capacity is high, reversible hydrogen adsorption and desorption performance is good and being favored because having.By LiH+LiNH 2the Li-N-H system of composition is the Typical Representative of metal nitrogen base hydride hydrogen storage system, and its reversible hydrogen adsorption and desorption capacity is 6.5wt.%, but its hydrogen discharging temperature and hydrogen desorption kinetics performance await further improvement.Current investigator, mainly through adding catalyzer, the approach such as cation-modified, makes its hydrogen discharging performance be improved, but its hydrogen discharging temperature is still higher than the temperature requirement of fuel cell use.Because the heat conductivility of Li-N-H system is poor, usually adopt traditional type of heating, its heat-up rate is comparatively slow, and observable index is comparatively large, seriously limits its practical application.
Microwave is the hertzian wave of a kind of range of frequency at 300 MHz to 300 GHz.When being in the material in microwave field and containing microwave absorbing medium, the energy that substance absorbs microwave carries out conducting self-heating.This type of heating is called microwave heating.Microwave heating is a kind of brand-new heat energy technology, and compared with traditional heating, microwave heating has the features such as heating efficiency is high, rate of heating fast, selectivity heating, globality heating; In addition, microwave heating also has catalyzed chemical reaction, reduces chemical reaction temperature, for chemical reaction creates the more favorably non-thermal effect such as thermodynamic condition.
In order to improve the hydrogen discharging performance of Li-N-H system, the present invention proposes a kind of Li-N-H of realization system and circulates under microwave and put the method for hydrogen fast.Add in Li-N-H system and can play the medium that katalysis can absorb again microwave, realize Li-N-H system by microwave heating and put hydrogen fast, in conjunction with the cycle performance that Li-N-H system is good, by the practical application of favourable promotion Li-N-H system hydrogen storage material.
Summary of the invention
Circulate under the object of this invention is to provide a kind of Li-N-H of realization system microwave and put the method for hydrogen fast.The method is simple, has both overcome the problem of Li-N-H system heat conductivility difference, has improve heating efficiency, facilitates again the hydrogen desorption kinetics performance of Li-N-H system.
To achieve these goals, the present invention adopts following technical scheme:
Circulate under realizing Li-N-H system microwave and put a method for hydrogen fast, it is characterized in that, at Li-N-H(mol ratio LiH:LiNH 2=1:1) in add a small amount of LiBH 4; LiBH 4content and Li-N-H content by mass percentage, LiBH 4content be 5 ~ 35%; There is following step:
A. LiH powder is taken by certain proportioning, LiNH 2powder, LiBH 4powder, powder LiH and LiNH 2mol ratio be 1:1, LiBH 4the mass percentage content of powder is 5 ~ 35%.Above-mentioned raw materials is placed in ball mill fully mix, ball material weight ratio in ball mill is 30:1, and the powder that namely every 1 g is heavy needs the abrading-ball that 30 g are heavy, and the speed of mainshaft of ball mill is 200 revs/min, countershaft rotating speed is-400 revs/min, and wherein "-" expression turns to contrary; Ball-milling Time is 2 ~ 4h, and ball milling 10-30 minute has a rest 1-30 minute; For preventing Powder Oxidation, carry out in the canned sample of sample weighing, ball milling and the glove box of sampling all under Ar atmosphere protection;
B. uniform for above-mentioned ball milling sample is shifted in microwave tube type oven, vacuumize and pass into high-purity argon gas protection, opening microwave power supply, power 400-3000W, sample is rapidly heated, and in 5 minutes, sample temperature can rise to more than 400 DEG C, makes Li-N-H system put hydrogen completely;
C. sample after ball milling is heated under microwave less than 300 DEG C carry out suction put hydrogen circulation, the LiBH in sample 4with LiNH 2reaction forms solid solution phase (LiNH 2) x(LiBH 4) (1-x), this solid solution phase is both as catalysis phase, and again as inhaling ripple phase, and absorbing property is better than LiBH 4, thus realize Li-N-H system and circulate under microwave and put hydrogen fast.
The microwave frequency adopted in above-mentioned steps b and c is 2.45GHz, and the field pattern of microwave is multimode field pattern.
Feature and the mechanism of the inventive method are as described below:
The present invention makes full use of the feature of microwave radiation, by adding LiBH 4as wave absorbing agent, achieve Li-N-H rapid temperature increases and put hydrogen rapidly under microwave action, both overcome heating efficiency in traditional heating mode low, heat the problems such as uneven, facilitate again the hydrogen desorption kinetics performance of Li-N-H system by the effect of microwave.The present invention makes full use of LiBH 4feature: LiBH during (1) ball milling 4play grinding aid effect, powder is mixed uniformly, and effectively can reduce the particle of Li-N-H; (2) LiBH 4with LiNH 2quaternary solid solution phase (LiNH is generated in mechanical milling process 2) x(LiBH 4) (1-x), N-H key is weakened, katalysis is played to the hydrogen of putting of Li-N-H system; (3) the quaternary solid solution phase (LiNH generated when microwave heating 2) x(LiBH 4) (1-x)again as inhaling ripple phase, compare LiBH 4there is better absorbing property, thus realize Li-N-H system and be rapidly heated under microwave and put hydrogen.This system is being put in hydrogen working cycle lower than 300 DEG C of microwave heatings, (LiNH 2) x(LiBH 4) (1-x)all the time deposit in the sample to which, thus realize Li-N-H system and can circulate to be rapidly heated under microwave and put hydrogen.And in practice, can also according to the demand by hydrogen amount, the power of adjustment microwave, thus change hydrogen discharging rate.
Compared with prior art, the present invention has following outstanding substantive distinguishing features and remarkable advantage:
Under microwave radiation, Li-N-H system temperature rise rate is fast, and heating efficiency is high, under 400W power microwave, is such as heated to 250 DEG C of times used be only 100s, and traditional heating method reaches uniform temp and needs 1700s under 800W power.The hydrogen discharging rate of Li-N-H system under microwave improves a lot compared with under traditional heating mode, such as with the addition of 7.6wt%LiBH 4sample in common heating furnace, only have the H of 1.2wt% in 10 minutes at 250 DEG C 2release, and under microwave heating, have the H of 3.2wt% 2release.LiBH 4with LiNH 2quaternary solid solution phase (LiNH is generated in mechanical milling process 2) x(LiBH 4) (1-x)because decomposition temperature is 330 DEG C, ensure that sample is put in hydrogen working cycle in the suction lower than 300 DEG C and all can put hydrogen at rapid temperature increases under microwave.
