Conclusions
-
1.
The strong chemisorption of the components of the reaction mixture in the methanol synthesis process on a SNM-1 catalyst has been determined by a thermal desorption method. There is no appreciable adsorption of CO and H2 on the reduced catalyst; water and CO2 form surface compounds appearing in the TD spectra as peaks with Tmax 360 and 300°C respectively.
-
2.
The surface compound of carbon dioxide is formed even when the catalyst is reduced with carbon monoxide. Its concentration increases when high-temperature chemisorption of CO2 is carried out.
-
3.
The main portion of H2 in the TD spectrum occurs as a result of oxidation of the reduced centers by water during TD.
-
4.
Water from the gas phase at 250°C is capable of almost entirely displacing CO2 from the surface of the SNM-1 catalyst.
