摘要

Ni-foam-structured CeO₂-NiO-Al₂O₃ catalysts to be used for oxidative dehydrogenation of ethane to ethylene (ODE) have been developed, via chemically etching a Ni-foam followed by CeO₂ modification. The CeO₂-NiO-Al₂O₃/Ni-foam catalysts are highly active and selective with promising stability. With the increase in CeO₂ loading up to 10 wt%, ethane conversion is increased monotonously while ethylene selectivity shows volcano-shaped evolution and reaches its maxima at 7 wt% CeO₂ loading. A high ethylene productivity of 425 g_Ethylene kg_cat^− 1 h^− 1 is achieved for a feed gas of C₂H₆/O₂/N₂ = 1/1/8 at 450 °C and a gas hourly space velocity of 18,000 cm³ g^− 1 h^− 1. Promotion effect of CeO₂ additive is also discussed.
