Definitions
- the present invention relates to a method for the reversible storage of hydrogen, alkali metals or their hydrides and aluminum metal being doped with transition metal catalysts being used as hydrogen storage materials.
- the disadvantages of the previous method of the SGK are that the preparation and purification of the commercial sodium alanate, the production of Na 3 AIH 6 or Na 2 LiAIH 6 and the subsequent doping in organic solvents are preparative and relatively complex and in most cases easy to use volatile, highly flammable (ether, pentane) and prone to peroxide (ether, THF) solvent required.
- the starting materials for their production can be used in the form of alkali metal hydrides or alkali metals (in particular NaH or Na), Al powder and dopants.
- the alanates formed from these starting materials in a hydrogenation step are immediately functional as H 2 stores and have improved storage properties compared to PCT / WO 97/03919.
- Na and Li alanates can be prepared by mixing the corresponding alkali metal hydrides (or alkali metals) and aluminum in ethers, amines and aliphatic or aromatic hydrocarbons, if appropriate in the presence of catalytic amounts of organoaluminum Compounds reacted with hydrogen under pressure.
- 3,138,433 (1964) describes, inter alia, a method for the preparation of NaAIH 4 from NaH, Al and hydrogen under pressure in THF, using Ti, Zr, Hf and Th tetrahalides as catalysts; in the only patent example contained therein, however, a yield of NaAIH of max. 21.8% stated.
- a direct synthesis of Na 3 AIH 6 is possible in 98% yield according to Inorg. Chem. 5 (1966) 1615, by reacting Na and activated Al powder in diglyme in the presence of Et 3 Al with hydrogen under pressure (350 bar).
- a synthesis of NaAIH 4 from the elements Na, AI and H is also possible in the absence of organic solvents according to Dokl. Akad.
- the alkali metal alanates prepared by the processes mentioned were not taken into consideration for the purposes of hydrogen storage.
- the preparation of the storage material according to the present invention is very simple and completely dispenses with organic solvents.
- the aluminum powder used in the present process is cheaper and easier to handle than the sodium alanate previously used. It was particularly surprising that the hydrogenation of aluminum in the presence of alkali metals or metal hydrides at temperatures well below the melting points of the metal / metal hydride starting materials involved and the metal alianate products, ie in solid form, succeeds (in contrast to the direct synthesis cited above) according to Dymova et al., Dokl. Akad. Nauk SSSR 215 (1974) 1369, English 256 "Direct Synthesis of Alkali Metal Aluminum Hydrides in the Melt").
- aluminum powder is mixed with powdered sodium hydride and mixed with catalytic amounts of titanium tetrabutylate.
- the mass obtained in this way can be directly reversible Hydrogen storage can be used. If Al and NaH are used in a molar ratio of 1: 1, NaAIH 4 is obtained in the hydrogenation, while Na 3 AIH 6 is obtained in a molar ratio of 1: 3 after the hydrogenation.
- Another particular advantage of the present process for the reversible storage of hydrogen is that, by simplifying the previously known method according to PCT / WO 97/03919, the desorption and absorption kinetics could be significantly improved.
- FIG. 2 shows the course of hydrogenation of a hydrogenation cycle according to the previous method at 170 ° C. and according to the present method at 118 ° C. and illustrates the clearly gained activity.
- FIG. 3 shows 33 hydrogenation / dehydrogenation cycles of a material according to the present method and prove the reversibility of the new materials.
- a typical storage material preparation according to the present invention is that aluminum powder, untreated or after briefly heating in vacuo to about 200 ° C., is stirred vigorously with finely powdered sodium hydride under a protective gas (eg argon). Subsequently, with stirring (or possibly with grinding), catalytic amounts of titanium tetra-n-butoxide (0.1 to 10 mol% based on aluminum, preferably 1 to 5 mol%) are added dropwise. In this way, a gray, slightly sticky, but still pourable powder mixture is obtained, which is introduced into an autoclave.
- the first step is to hydrogenate under pressures between 5 and 150 bar and temperatures between 20 and 200 ° C. The mixture is then dehydrated against elevated pressure or normal pressure at temperatures between 50 and 250 ° C.
- the aluminum is preferably used in the form of a fine cut (see Examples 1 and 5: surface It. BET measurement 12.2 or 2.0 m 2 / g).
- the aluminum used can optionally be preactivated by grinding, exposure to ultrasound or chemical activation.
- sodium hydride or sodium other alkali metal hydrides or alkali metals (in particular Li and K) can be used individually or in combinations.
- the molar ratio between aluminum and alkali metal can vary between 1: 0.3 and 1: 5. If aluminum and Na or NaH are used in a molar ratio of - 1: 1 or - 1: 3, the hydrogenation gives NaAIH 4 or Na 3 AIH 6 .
- the alkali metals or their hydrides can optionally be pretreated before use by grinding or exposure to ultrasound.
- Transition metals or transition metal compounds or alloys of groups 3-11 of the PSE and rare earth metals are used individually or in combinations, which can be bound to elements of groups 14-17 or hydrogen, as catalysts.
- the transition metal or rare earth metal compounds are preferably used in the form of halides, hydrides, alcoholates, amides or organometallic compounds. Halides, alcoholates and organometallic compounds of titanium, zirconium and rare earth metals are particularly preferred.
- Example 1 Al and NaH powder mixture doped with titanium tetra-n-butoxide as a reversible hydrogen storage; 33-cycle test
- the aluminum used was an AI cut (Lunasol) from the Frankfurt bronze paint and sheet metal factory Julius Schopflocher AG with a surface area of 12.2m 2 / g (It. BET measurement).
- the NaH was finely pulverized in a glass ball mill.
- the aluminum powder was briefly heated to 200 ° C. at 0.1 mbar (aluminum content according to elementary analysis by H. Kolbe, Mülheim a.d.Ruhr: 91.7% by weight).
- Fig. 1 shows the course of dehydrogenation (8th cycle, 3.96% by weight H 2 ) compared to the prior art.
- Fig. 3 shows the dependence of the hydrogen storage capacity (measured using the amount of H 2 released during dehydrogenation) on the number of cycles.
- the storage material was removed from the autoclave in hydrogenated form and examined by infrared spectroscopy.
- the IR spectrum shows AIH 4 and AIH 6 bands, in addition to weak CH and CO bands (alcoholate groups).
- Example 2 Al and NaH powder mixture doped with titanium tetra-n-butylate as a reversible hydrogen storage using untreated aluminum cut
- the storage material preparation was carried out analogously to Example 1, but the untreated commercial product was used here instead of the aluminum heated in a vacuum.
- the material was examined in 7 cycles and reached a storage capacity of 3.7% by weight H 2 in the 3rd hydrogenation process and 3.6% by weight H 2 in the 7th hydrogenation step.
- Example 3 Al and NaH powder mixture doped with ⁇ -TiCI 3 as a reversible hydrogen storage agent
- the storage material preparation was carried out analogously to Example 1, but the aluminum grinding was not baked in a vacuum, but rather before it was used Mechanically grind in a glass ball mill. Instead of Ti (OBu) 4 were
- the material was cyclized and reached a capacity of 2.5% by weight H 2 in the 1st hydrogenation and 2.9% by weight in the 5th hydrogenation step (at 135 ° C / ⁇ 140bar)
- the storage material preparation was carried out analogously to Example 1, but the aluminum grinding was not baked in a vacuum, but was mechanically ground in a glass ball mill before being used.
- the molar ratio between aluminum and sodium hydride was 1: 2.9.
- the material reached a capacity of 2.2 wt .-% H 2 and 5.
- hydrogenation step (at 117 ° C / 35 bar) 1, 5 wt .-% H 2 in the 1st hydrogenation.
- Example 5 Al and NaH powder mixture doped with titanium tetra-n-butylate as reversible hydrogen storage using spherical Al powder ⁇ 20 ⁇
- the storage material preparation was carried out analogously to Example 2, with a spherical Al powder ( ⁇ 20 ⁇ ) from Aldrich (surface according to BET measurement: 2.0 m 2 / g) being used in the untreated form instead of the Al grinding.
