Title:
METHOD FOR PREPARING HYDROGEN GAS
Document Type and Number:
WIPO Patent Application WO/2018/216886
Kind Code:
A1
Abstract:
A method for preparing hydrogen gas, according to embodiments of the present invention, comprises the steps of: generating carbon dioxide (CO2) by using steelmaking slag; generating hydrogen gas by reacting a gas containing methane (CH4) with carbon dioxide (CO2); and recovering the generated hydrogen gas. Therefore, according to embodiments of the present invention, hydrogen gas can be produced by recycling steelmaking slag. In addition, since steelmaking slag is used as a material for producing hydrogen gas, the amount of steelmaking slag to be reclaimed can be reduced, thereby enabling environmental pollution to be reduced.
