Today, CO is mostly converted by addition of O2 and preferential oxidation, but H2 is then also partly oxidized. An alternative is selective CO methanation, studied in this work. CO2 methanation is then a highly unwanted reaction, consuming additional H2. The kinetics of CO methanation in CO2...
The aforesaid mechanism involves different reaction steps: the first is the formation of a chemical bond between the reagents (CO, O2 or H2) and the catalyst surface; then the formation and the desorption of products (CO2 and H2O) take place with the generation of oxygen vacancies in the ...
