Document Type and Number:
WIPO Patent Application WO/2021/060215
Kind Code:
A1
Abstract:
The present invention relates to a hydrogen gas production method comprising: a first step of producing a mixed gas containing hydrogen and carbon dioxide from a hydrogen-storing agent by a dehydration reaction using a catalyst in a reactor; a second step of producing a gas having a high hydrogen concentration from the mixed gas by purification; a third step of separating a solution in the reactor into a solution enriched in the catalyst and a permeate through a separation membrane unit; and a fourth step of supplying the solution enriched in the catalyst to the reactor and reuse the solution in the first step.
