Abstract
The process of oxidation of gaseous CH3OH by N2O was carried out over an Ag-Fe2O3-cenosphere catalyst whose structure can be defined as double shell-core catalyst. Preparation of the catalyst was carried out in two stages: thermal decomposition of Fe(CO)5 at above 160°C and then electroless Ag plating. The process of methanol degradation by N2O was carried out in a fluidized bed reactor. The study confirms that it is possible to achieve complete degradation of N2O and CH3OH for the obtained catalyst at above 450°C when the contact time of the reactants with the catalyst is approximately 6 second and when the substrates are used in stoichiometric ratios. More than 60% of the hydrogen contained in CH3OH can be converted to molecular hydrogen at 500°C with a ratio of N2O/CH3OH not greater than 0.6 and with a contact time of reactants with the catalyst of approx. 6 seconds.
