Organic hydrogen storage material dehydrogenation catalyst, support for the catalyst, hydrogen-storage alloy, and process for providing high-purity hydrogen gas

A process of providing high-purity hydrogen gas, comprising:

• S1:
• contacting an organic liquid hydrogen-storage material with a dehydrogenation catalyst to obtain a dehydrogenation reaction product containing hydrogen gas;
• S2:
• cooling the dehydrogenation reaction product to obtain a liquid product and a hydrogen-rich gas product, and collecting the liquid product;
• S3:
• contacting the hydrogen-rich gas with a hydrogen-storage alloy to obtain a hydrogen-containing alloy, collecting an unadsorbed gas, and optionally removing an organic substance in the hydrogen-containing alloy storage container;
• and
• S4:
• heating the hydrogen-containing alloy to release a hydrogen gas,
• wherein the hydrogen-storage alloy is selected from the group consisting of:
