Oxidative conversion of ethane involving lattice oxygen of molybdenum systems modified with aluminum, gallium, or yttrium oxide

Resumo

Oxidative conversion of ethane on the molybdenum oxide MoO₃ mixed with 0–95% Al₂O₃, Ga₂O₃, or Y₂O₃ has been studied in the pulse mode at 600°C. It has been revealed that the components of these systems undergo strong interaction, which leads to enhanced ethane conversion and an increased selectivity for ethylene with a decrease in the MoO₃ content. The 5%MoO₃–95%Al₂O₃ system has proved the most effective in the oxidative dehydrogenation of ethane, with the selectivity for ethylene reaching 90% at an ethane conversion of 30 wt %.
