Abstract. Ni-, Cu-, and Fe-loaded acidic and basic Y zeolites were synthesized, and their catalytic properties for oxidative dehydrogenation of ethane (ODHE) to ethylene were characterized. Acidic Ni-loaded Y zeolite exhibits an ethylene productivity of up to 1:08 gC2H4 gcat-1 h-1 with a selectivity of 75%. Acidic Cu- and Fe-loaded Y zeolites have an ethylene productivity of up to 0:37 gC…
