Title:
CARBON MONOXIDE PRODUCTION METHOD AND DEVICE USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/037652
Kind Code:
A1
Abstract:
Provided are: a CO production method that is realized through CO2-hydrogen reduction and that can be conducted at a low-temperature condition without using a complex oxide or a metal species that leads to an increase in cost; and a device used for the method. This carbon monoxide production method comprises: (a) a step for preparing an absorption conversion catalyst that includes a carrier and at least one additive being supported by the carrier and selected from the group consisting of alkali metals and alkaline earth metals and that substantially does not contain Ni, Fe, Co, Cr, Cu, Ru, In, Rh, Pt, Au, and Pd elements; (b) a step for bringing a gas containing carbon dioxide into contact with the absorption conversion catalyst to occlude carbon dioxide to the absorption conversion catalyst; and (c) a step for bringing the absorption conversion catalyst having carbon dioxide occluded thereto, into contact with a reductive gas to generate carbon monoxide.
