Embodiment Construction

[0022] Figure 1-4 A hydrate hydrogen storage device based on the memory effect is demonstrated. The whole device is composed of two end caps, inner and outer sleeves, a porous medium block containing molecular sieves and a filter. The end cover and the inner cylinder form a high-pressure reaction chamber, and a porous medium block containing molecular sieves is placed in the middle for the formation and decomposition of hydrates; the two end covers form a sandwich between the inner and outer cylinders, and a circulating cooling medium is introduced to control Temperature promotes THF and H 2 Binary hydrate generates hydrogen storage, or passes through a circulating heating medium to promote its decomposition, or is evacuated to facilitate storage and transportation; due to the volatility and toxicity of THF, the filter device adopts No. 3 (Type A) filter poison tank for gas outlet Filtration to ensure the safe use of hydrogen; the water inlet is used to inject THF aqueous s...

Abstract

The invention discloses a memory-effect-based hydrate hydrogen storage device and a memory-effect-based hydrate hydrogen storage method, and belongs to the technical field of scientific instruments for petroleum. The hydrogen storage device and the hydrogen storage method are rapid, safe, low in cost and convenient to use, the design pressure is 0 to 20Mpa, and the design temperature is -20 to 30 DEG C. In order to strengthen the strength of the device and meet hydrogen storage, transportation and utilization requirements, the device is integrally made from a titanium alloy material, and is designed into a double-layer sleeve structure, wherein end covers and an inner barrel form a high-pressure resistant reaction chamber for generating and decomposing hydrate; the temperature of the inner barrel is controlled through a circulating cooling agent in an interlayer, and the interior of the interlayer can also be vacuumized to facilitate the storage and transportation of hydrogen; a filter can be used for filtering THF (tetrahydrofuran) gas which is volatilized during the release of hydrogen. According to the device and the method, THF hydrate decomposition water can be used for generating THF hydrate according to a memory effect, so that the reaction speed is greatly increased; the device is compact in structural design, recyclable, convenient to operate, simple and applicable.

Description

technical field [0001] The invention relates to a device based on memory effect, which belongs to the technical field of petroleum scientific research instruments. Background technique [0002] With the development of society, human beings have an increasing demand for energy. As a clean and high-quality energy, hydrogen energy is of great significance to the sustainable development of human beings. At present, the storage of hydrogen energy is the main bottleneck in the development of hydrogen economy. The requirements of the hydrogen energy industry for hydrogen storage are that the hydrogen storage system should be safe, large in capacity, low in cost, and easy to use. The main hydrogen storage materials and technologies currently used or under research include: high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, metal hydride hydrogen storage, carbon-based material hydrogen storage, organic liquid hydride hydrogen storage, etc. Most of thes...
