Resumen
[EN] Removal of trace amounts of C2H4 from air streams at low temperature is technologically important for fruit preservation in warehouses. For that reason, a systematic quantitative and comparative study of Ag-zeolites for trace ethylene adsorption has been carried out. Combining characterization results with trace ethylene adsorption in a fixed-bed system have allowed to stablish a correlation between Ag delta+ species present in the zeolites and trace ethylene adsorption capacity. Among the zeolites studied, silver exchanged zeolites with -CHA (SSZ-13) and -LTA (5A) frameworks exhibited the most stable and highly dispersed silver sites, with an excellent potential for indoor environmental control of trace ethylene at 0 degrees C.
