Exemplified by system, problems with is there is in actual use：1) cost of raw material is expensive；2) precious metal catalysts such as palladium, ruthenium into
This height, immobilized rear catalyst service life are short (because hydrolysis is to occur to react in the very exothermic of catalyst surface)；3)
Reaction product kodalk (NaBO2) easy blocking pipeline；4) recycling utilization of byproduct of reaction is difficult；5) hydrogen storage fuel solution
Stability it is poor because NaBH4A metastable state is in strong alkaline aqueous solution, it is easy to which hydrogen is released in spontaneous generation hydrolysis
Gas, very big potential safety hazard be present, while be also unfavorable for storing for a long time.These defects cause the extensive use of this method by
To a definite limitation.
Metallic aluminium is widely used material in daily life, from basic chemical reaction 1 gram of metallic aluminium of knowledge and water
Reaction can produce 1.24 standards and rise hydrogen.Aluminium rich reserves in the earth's crust, and metallic aluminium can regenerate with water reaction product
Recycle, therefore scale, inexpensive hydrogen can be obtained come hydrogen making using metallic aluminium especially waste aluminium and water reaction
Source.Hydrogenation stations construction of the popularization and application based on aluminium hydrolysis hydrogen producing technology, can greatly promote fuel cell car infrastructure
Build.Because aluminium surface generally has oxide-film, hydrogen production reaction usually requires to carry out under the conditions of sodium hydroxide catalyst is existing,
Control the condition of reaction, caused hydrogen can be supplied directly to fuel cell or other need hydrogen storage equipment.But in actual behaviour
In work, aluminum hydrogen reaction system be there are problems that a lot, and for example course of reaction is difficult to control, and can not realize that continuous hydrogen production etc. is asked
