Tīmeklis2010. gada 14. dec. · The effect of H2O on N2O decomposition in Fe/ZSM-5 catalyst was investigated by steady-state kinetics, transient response methods, in situ Raman, and IR spectroscopies. Fe/ZSM-5 catalysts show very high activity in N2O decomposition but are deactivated rapidly when trace amounts of water are present. … Tīmeklis2014. gada 1. okt. · Abstract Methane oxidation by N 2 O at 200 °C and below was shown to proceed in a quasicatalytic mode resulting in product accumulation on FeZSM-5 surface. Methanol that formed via methane oxidation by α-oxygen, CH 4 + (Fe III –O − ) α , migrated from α-sites, initiating new reaction cycles. At 200 °C, a 4-h run …
