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

Oxidative conversion of ethane on the molybdenum oxide MoO 3 mixed with 0–95% Al 2 O 3 , Ga 2 O 3 , or Y 2 O 3 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...

Zusammenfassung:Oxidative conversion of ethane on the molybdenum oxide MoO 3 mixed with 0–95% Al 2 O 3 , Ga 2 O 3 , or Y 2 O 3 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 MoO 3 content. The 5%MoO 3 –95%Al 2 O 3 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 %.
