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.

Abstract

The present invention relates to carbon nanotube hydrogen-storing and coating method. The present invention includes two parts of hydrogen storing and coating. After purification, washing, drying and shearing, the coating medium is fed to coating tank and carbon nanotube is fed to hydrogen storing tank for storing hydrogen. The carbon nanotube after storing hydrogen is fed into the coating tank via pressure valve for coating, and after coating, the releasing valve is opened to restore the normal pressure in the coating tank, and the coated hydrogen storing carbon nanotube in dry state is taken out. The present invention realizes the high pressure hydrogen storing and normal pressure transportation, with the hydrogen storing amount being able to be calculated precisely. The present invention is suitable for adsorption and coating of various kinds of nanometer, submicron and micron material.

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...
