Effect of Co-Mo nitride catalyst over carbonaceous support in the Oxidative dehydrogenation of Ethylbenzene

Key Points

• The study aims to assess the impact of Co3Mo3N catalysts on the oxidative dehydrogenation of ethylbenzene.
• Conducted oxidative dehydrogenation under atmospheric pressure.
• Used 10 and 20 wt% Co3Mo3N catalysts supported on activated carbon.
• Employed gas flows of N2, CO2, and CO2-N2 mixtures.
• Characterized catalysts using XRD, TPR, and BET surface area techniques.
• The 10 wt% Co3Mo3N catalyst showed superior activity compared to the 20 wt% catalyst.
• Better dehydrogenation activity noted in 10 wt% catalyst with CO2-N2 gas flow.
• Synergistic effects of ammonia synthesis and reverse water–gas shift reaction enhanced performance.
