Abstract
A method for enriching carbon dioxide and hydrogen by water-gas shift coupling of blast furnace gas is disclosed in the present application, belonging to the technical field of flue gas resource utilization, where the method includes: purifying the blast furnace gas by a dry purification method, followed by heating and mixing with water vapor, allowing for water vapor shift coupling reaction under an action of a catalyst to obtain a mixed gas of carbon dioxide and hydrogen; adsorbing the mixed gas of carbon dioxide and hydrogen with a carbon dioxide adsorbent and desorbing to obtain carbon dioxide; introducing a gas not adsorbed by the carbon dioxide adsorbent into a molecular sieve adsorbent to remove impurities, then obtaining a hydrogen. Blast furnace gas is used as raw material, and hydrogen is provided for subsequent hydrogen smelting while realizing carbon enrichment in the blast furnace process.
