example 1

[0036] In a glove box filled with argon, weigh the ZrCo-based alloy that was used for the first time or after performance degradation, and then put it into the reactor, and then use a vacuum pump to vacuum the reactor. This operation can make the ZrCo-based alloy In the protective atmosphere of inert gas (argon), it prevents oxidation in contact with air and affects its hydrogen absorption performance. While the reactor was evacuated, it was also heated up to 300°C at a heating rate of 5°C / min. After the temperature of the reaction kettle reached 300° C., vacuum was continued for 60 minutes, and then the reaction kettle was cooled to room temperature along with the furnace, and the reaction kettle was evacuated while cooling down. By heating, cooling and vacuuming the reactor, the ZrCo-based alloy can be prepared for hydrogen absorption.

[0037] Then, fill the reactor with 80kPa high-purity hydrogen to absorb hydrogen. The hydrogen absorption curve is as follows figure 2 Shown...

example 2

[0039] As in Example 1, in a glove box filled with argon, weigh the ZrCo-based alloy that was used for the first time or after performance degradation, and then put it into the reactor. Then the reactor was evacuated and heated at 10°C. A heating rate of / min raises the temperature of the reactor to 500°C. After the temperature of the reaction kettle reached 500° C., vacuum was continued for 30 minutes, and then the reaction kettle was cooled to room temperature along with the furnace, and the reaction kettle was evacuated while cooling down.

[0040] Fill the reactor with 80kPa high-purity hydrogen to absorb hydrogen. The hydrogen absorption curve is as follows figure 2 Shown. After the ZrCo-based alloy is saturated with hydrogen absorption (hydrogenation products such as image 3 As shown), vacuum the reactor again, and at the same time raise the temperature of the reactor to 500°C at a heating rate of 10°C / min. After the temperature of the reactor reaches 500°C, continue to ...

example 3

[0043] As in Example 1, in a glove box filled with argon, weigh the ZrCo-based alloy that was used for the first time or after performance degradation, and then put it into the reactor, and then evacuate the reactor at 8°C / The heating rate of min raises the temperature of the reactor to 500°C. After the temperature of the reaction kettle reached 500°C, vacuum was continued for 50 minutes, and then the reaction kettle was cooled to room temperature along with the furnace, and the reaction kettle was evacuated while cooling down.

[0044] Fill the reactor with 1 bar of high-purity hydrogen to absorb hydrogen. The hydrogen absorption curve is as follows figure 2 Shown. After the ZrCo-based alloy is saturated with hydrogen absorption (hydrogenation products such as image 3 Shown), vacuum the reactor again, and at the same time raise the temperature of the reactor to 400℃ at a heating rate of 5℃ / min. After the temperature of the reactor reaches 400°C, continue to vacuum for 60 min...

Abstract

The invention discloses a method for rapidly and efficiently activating a ZrCo-based hydrogen isotope storage material. The method includes the steps that firstly, ZrCo-based alloy which is preliminarily used or attenuated in performance is subjected to vacuumizing pretreatment within the temperature range from the indoor temperature to 500 DEG C; secondly, 10 kPa to 500 kPa of high-purity hydrogen gas is injected and the pretreated ZrCo-based alloy is subjected to hydrogen absorption treatment within the temperature range from the indoor temperature to 400 DEG C; and thirdly, the ZrCo-based alloy absorbing hydrogen to be saturated is dehydrogenized within the temperature range from 350 DEG C to 500 DEG C, so that the activated ZrCo-based alloy is obtained. The method is simple and prominent in activating effect, the activating time of the ZrCo-based alloy in the actual application process can be effectively shortened, the ZrCo-based alloy has the brand-new hydrogen isotope storage activity after being preliminarily used or attenuated in performance, and the method has the important significance in promoting application and popularization of the ZrCo-based alloy in the hydrogen isotope storage field.

Description

Technical field [0001] The invention relates to the technical field of hydrogen isotope storage and supply, in particular to a method for quickly and efficiently activating ZrCo-based hydrogen isotope storage materials. Background technique [0002] Energy is the material basis for the survival and development of human society, and a clean environment is the guarantee for the sustainable development of human society. In recent years, the energy crisis and environmental problems caused by the excessive development and use of fossil energy have become the focus of attention all over the world. [0003] The development of a clean and renewable new energy source has become an urgent task. Nuclear fusion energy is receiving widespread attention due to its cleanliness, safety, and permanence. Fusion reactors use hydrogen isotope gas as nuclear fuel. For example, the International Thermonuclear Experimental Reactor (ITER) burns deuterium-tritium plasma to release huge fusion energy. Si...
