Manufacturing method of corrugated rare earth hydrogen storage material

Abstract

The invention relates to a manufacturing method of a corrugated rare earth hydrogen storage material, which comprises the following steps: grinding titanium oxide powder, boric oxide powder, niobium dioxide powder and rhenium oxide powder into powder with the particle size of 50-80 nanometers, weighing according to a ratio, blending, and fusing to obtain a material A for later use; weighing nano zinc oxide and nano magnesium oxide according to the formula, and mixing to obtain a material B for later use; and weighing polyvinyl chloride, activated carbon and titanium oxide powder according to the formula, blending, putting the mixture into a charging barrel of an extruder after blending is finished, heating and extruding a corrugated material, and then preparing the corrugated-structured rare earth hydrogen storage material after manufacturing and assembling. It is ensured that the rare earth hydrogen storage material can reversibly absorb, store and release a large amount of hydrogen in the normal-temperature state, safe use of hydrogen energy in power generation and combustion links is promoted, the use efficiency of green energy is improved, and meanwhile, the material has the advantages of being high in product yield, low in cost, easy and convenient to operate, long in service life, efficient, capable of saving energy and environmentally friendly, and has wide application value.

Description

technical field [0001] The invention belongs to the hydrogen energy storage industry, relates to materials for the hydrogen storage link, and particularly relates to a manufacturing method of corrugated rare earth hydrogen storage materials. Background technique [0002] Hydrogen energy is known as the ultimate energy source for mankind in the 21st century. The hydrogen energy industry includes three links: hydrogen production, hydrogen storage and application. Hydrogen production is the basis of hydrogen storage, and hydrogen storage is currently the bottleneck facing the industry. At present, there are many hydrogen storage products on the market. Generally, there are methanol hydrogen storage, high-pressure hydrogen storage, liquefied hydrogen storage, solid-state adsorption hydrogen storage and metal hydride hydrogen storage. Except for high-pressure hydrogen storage, which has been commercialized, other hydrogen storage products are currently Still in the experimental ...

Problems solved by technology

[0006] The task of the present invention is to provide a method for manufacturing corrugated rare earth hydrogen storage materials, which involves grinding titanium oxide, boron oxide, niobium dioxide and rhenium oxide powders into a particle size of 50-80 nanometers, weighing, blending, and merging according to the proportion Finally, it is used as material A for standby; nano-zinc oxide and nano-magnesium oxide are weighed and mixed according to the formula and then used as material B for future use; then polyvinyl chloride, activated carbon and titanium oxide powder are weighed according to the formula and blended, and the blending is completed and loaded into the extruder The extruding cylinder is heated and extruded corrugated material, and then the rare earth hydrogen storage material with corrugated structure is formed after production and assembly, which has the performance of absorbing and releasing hydrogen at normal temperature and normal pressure, which solves the problem of hydrogen storage produced by traditional technology. The product process is complicated and the effect is relatively general
