(326b) Ethane Oxidative Dehydrogenation in Microwave-Heated Fixed Bed and Structured Catalyst Reactors
AIChE Annual Meeting
Friday, November 20, 2020 - 8:15am to 8:30am
In this talk, we will present ethane oxidative dehydrogenation with carbon dioxide over Ga2O3/Al2O3 catalyst to provide insights into microwave reactor design. Our results showed that the heating rate with microwaves increases at least 10 times compared to conventional heating. Next, we compare the performance of fixed beds and structured beds of different characteristic features. The temperature uniformity is enhanced in the structured bed due to increased heat transfer. IR thermal camera shows a standard deviation in the temperature distribution of 5.0 °C in the structured bed and of 12 °C in the fixed bed. The structured bed is more stable as the reactivity dropped only 4% after 2 hr of reaction vs. 18% in the case of a fixed bed. Lastly, we will compare a merit index of microwave and conventional heating reactors to assess the potential of microwave technology for light olefins production.
