Problems solved by technology

This technology adopts the combination technology of MOF material and PCM material, which helps to increase the adsorption capacity and regulate the temperature change of the adsorbent bed layer, but the molding technology of MOF material will easily lead to the decline of the physical and chemical properties of the material, which affects the hydrogen storage capacity; PCM material packaging The system occupies the adsorbent space, resulting in limited adsorption capacity

Embodiment 1

[0031] The metal-organic framework material uses zirconium-based metal-organic framework material UiO-66, and UiO-66 is synthesized by solvothermal method: 15mmol ZrCl 4 and 15mmol of phthalic acid were dissolved in 115mL of DMF solvent, and ultrasonically treated for 10min; then the reaction solution was placed at 120°C, kept at a constant temperature for 24h, cooled to room temperature, and the solvent was removed by suction filtration, and the filter cake was washed once with DMF and methanol respectively , dried at 80°C for 12h to obtain UiO-66 powder.

[0032] Weigh 100g of UiO-66, 30g of paraffin wax with a phase transition temperature of 45°C and 5g of deionized water, and prepare a core-shell hydrogen storage material through a centrifugal coating granulator. Among them, the power of the centrifugal coating granulator is 5KW, the working room temperature is 40°C, and the rotating speed of the turntable is 230rpm. A spherical core-shell hydrogen storage material with a...

Embodiment 2

[0035] In Example 1, lauric acid with a phase transition temperature of 45° C. was selected to replace paraffin wax with a phase transition temperature of 45° C., and other reaction conditions and material compositions were kept unchanged to obtain the adsorption storage release system B.

Embodiment 3

[0037] In Example 1, neopentyl glycol with a phase transition temperature of 45° C. was selected to replace paraffin wax with a phase transition temperature of 45° C., and other reaction conditions and material compositions were kept unchanged to obtain an adsorption storage release system C.

Abstract

The invention relates to a hydrogen adsorbing, storing and releasing system. The system comprises a closed container which is filled with a filling material and a heat conducting component, wherein the filling material is a core-shell type hydrogen storing material; a core layer is made of a phase-change energy storing material, and the shell layer is made of a metal organic framework structure; at least two layers of stainless steel filtering nets are arranged between the top part of the container and the filling material; and a filtering membrane is arranged between the filtering nets. According to the system, a traditional storing and releasing system structure is improved; the core-shell type hydrogen storing material and the heat conducting component are adopted, so that the hydrogenstoring capacity and the hydrogen storing-releasing efficiency is improved; and the influence of heat effect in hydrogen adsorbing-desorbing process can be effectively reduced. The hydrogen adsorbing,storing and releasing system is applicable to vehicle mounting of a hydrogen energy and can also be used for massively adsorbing and recovering industrial waste hydrogen resources.

Description

technical field [0001] The invention belongs to the technical field of gas adsorption storage, and specifically relates to a hydrogen adsorption storage release system and its application, more specifically, to a hydrogen adsorption storage release system containing a core-shell type hydrogen storage material. Background technique [0002] With the increasingly serious energy and environmental pollution, the use of renewable, non-polluting energy to replace fossil fuels has become an urgent problem to be solved in social development. Due to the advantages of high calorific value, environmental friendliness, and recyclability, hydrogen energy has been highly valued by the government and energy utilization departments. Reducing the cost of hydrogen production and developing safe and efficient hydrogen storage technologies are two major challenges facing the utilization of hydrogen energy, and the latter is also a technical difficulty in the development of hydrogen-powered vehi...
