METHOD OF PRODUCING CARBON MONOXIDE FROM CARBON DIOXIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing CO from CO2, which is capable of efficiently producing CO with a simple equipment using CO2 easy to obtain as a raw material. SOLUTION: The method is for producing CO from CO2 and CO2 is catalytically reduced with H2 in the presence of a reverse CO shift catalyst using Fe and Cr as the active components or a reverse CO shift catalyst using activated alumina as the active component at 500-850 deg.C to produce CO and steam, the produced gas is cooled to separate steam as condensed water and CO is separated and recovered using a PSA method 6.
