Description

technical field [0001] The invention relates to an unsaturated organic matter cycle hydrogenation energy storage device, which belongs to the field of electrocatalytic materials and chemical equipment. Background technique [0002] Under the dual background of energy crisis and environmental pressure, countries all over the world have more urgent demand for green energy. Hydrogen energy has attracted widespread attention due to its advantages of cleanness and pollution-free, high calorific value and wide range of sources. The requirements of the hydrogen energy industry for hydrogen storage are generally that the hydrogen storage system should have the advantages of safety, large capacity, low cost, and convenient use. However, in most energy storage devices, such as high-pressure hydrogen storage and liquefied hydrogen storage, although there are many advantages, they also have disadvantages such as poor economy, high energy consumption, large evaporation loss, and unsafe ...

AI Technical Summary

Problems solved by technology

However, in most energy storage devices, such as high-pressure hydrogen storage and liquefied hydrogen storage, although there are many advantages, they also have disadvantages such as poor economy, high energy consumption, large evaporation loss, and unsafe work; the advantages and disadvantages of metal hydride hydrogen storage technology The performance depends on the solution of the mass transfer and heat transfer problems inside the storage and transportation containers, so there are more stringent and higher requirements for the device; and the hydrogen storage of organic hydrides is realized by the reversible reaction of unsaturated liquid organic matter and hydrogen Storage and release of hydrogen, but its device configuration is critical

[0003] Chinese invention application ZL200410033882.8 and CN201710321059.4 respectively disclose a hydrogenation device. The former mainly produces hydrogen by electrolysis of dilute sulfuric acid, and then brings benzene to the surface of the SPE membrane electrode through the carrier gas for reaction. Due to the comparison of the flow rate of the carrier gas Fast, the reaction product is collected after only one reaction at the membrane electrode, resulting in insufficient reaction, hydrogenation efficiency and target product content are not up to the actual production requirements; the latter has low pressure resistance, because its hydrogenation process is in the It is carried out under a certain high-pressure environment, the equipment investment and energy consumption are high, and the actual operation is more dangerous

[0004] Usually, the strength, pressure resistance and material requirements of the hydrogen storage container are relatively high. A large amount of energy must be consumed in this process, and the volume energy density is also low. These devices have low cost performance, high energy consumption, evaporation loss, and no safety and other disadvantages
