Title:
CARBON DIOXIDE SEPARATION/CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/181678
Kind Code:
A1
Abstract:
This carbon dioxide separation/conversion device comprises: one or more separation units (10) for separating carbon dioxide from a carbon dioxide-containing gas to obtain a carbon dioxide-enriched gas; a reaction unit (30) that comprises a catalyst for absorbing and converting carbon dioxide in the carbon dioxide-enriched gas, causes absorption of carbon dioxide in the carbon dioxide-enriched gas by the catalyst, and obtains a post-conversion gas including a conversion product from the carbon dioxide absorbed by the catalyst and hydrogen; and a hydrogen delivery unit (40) that delivers hydrogen to the reaction unit (30), wherein the separation unit (10) comprises one or more separation membrane modules including a separation membrane that separates carbon dioxide from a gas containing carbon dioxide, and a separation membrane module connection unit, which is connected to each separation membrane module and includes a carbon dioxide delivery port through which the carbon dioxide-enriched gas is discharged.
