WebApr 13, 2024 · Abstract The study investigates the potential for promoting V2O5/Al2O3 catalysts for selective catalytic reduction of nitrogen oxides with ammonia (NH3-SCR). It was found that the activity of low-V2O5 (2–4 wt %) catalysts can be markedly enhanced (by a factor of 3–4) by their promotion with tungsten oxide. It was shown that a promoted … WebJan 15, 2024 · Pt/Al 2 O 3 catalyst has also shown to be more active when the O 2 /CH 4 molar ratio was varied from the oxygen-rich to methane-rich conditions [48]. So far, many studies have been performed to characterize the performance of catalytic methane combustion, but mostly in conventional fixed-bed reactors [51], [52] or monolithic reactors …
