Carbon nanotube hydrogen-storing and coating method

Abstract

The invention relates to a carbon nanotube hydrogen storage and a coating method thereof. It includes two parts: hydrogen storage and coating. Purification, washing, drying, and shearing pretreatment are performed first, and then the coating medium is sent to the coating tank, and the carbon nanotubes are sent to the hydrogen storage tank for carbon nanotube hydrogen storage. Driven by the air flow, the hydrogenated carbon nanotubes enter the coating tank through the pressure valve to coat the hydrogen storage carbon nanotubes. After the coating is completed, the dispersion valve is opened to restore the coating tank to normal pressure, and the coated storage tank is taken out. Hydrogen carbon nanotubes are coated hydrogen storage carbon nanotubes in a dry state. The invention realizes the purpose of high-pressure hydrogen storage and normal-pressure transportation of carbon nanotubes, can perform a relatively accurate calculation of the hydrogen storage capacity of carbon nanotubes, thereby achieving the purpose of double verification, and is suitable for all nano, sub-micron and micron Material adsorption and coating, the coated hydrogen storage carbon nanotubes can be used as a beneficial supplementary energy source for propellants in solid rocket propellant or gunpowder, and can also be used in energy batteries.

Description

a technical field [0001] The invention relates to a nano material hydrogen storage and coating technology after hydrogen storage, in particular to a carbon nanotube hydrogen storage and coating method. Two background technology [0002] Hydrogen energy is an inexhaustible renewable clean energy, but the storage and transportation of hydrogen energy is an important factor restricting the utilization of hydrogen energy. At present, the main methods of hydrogen energy storage and transportation are: liquefaction storage and transportation method, compressed storage and transportation method, solid hydrogen-liquid hydrogen mixed storage and transportation method, metal hydride storage and transportation method, organic liquid hydride hydrogen storage, inorganic compound hydrogen storage, activated carbon adsorption hydrogen storage, etc. These hydrogen storage methods all have low mass hydrogen storage capacity (about 2%wt-3%wt), which cannot meet the requirements of power energ...

AI Technical Summary

Problems solved by technology

Of these two methods, the former is greatly affected by the ambient temperature, and the latter is greatly affected by the system pressure. It can neither accurately calculate the amount of hydrogen absorbed by carbon nanotubes nor solve the problem of hydrogen energy storage under normal pressure.
