(615d) Investigation of Microwave Interactions with Nickel Based Autothermal Reforming Catalysts

Microwaves have been utilized in a vast array of processes over the past 60 years. The ability to efficiently generate microwave radiation has led to energy savings in many drying and heating operations. Past research into zeolite and catalytic systems has explored the effects of microwaves on adsorbate equilibriums with the goal of altering equilibrium states. In catalyst systems microwave radiation has been shown to increase reaction rates, lower the bulk temperature at which reactions occur and assist in the desorption of sulfur. Despite beneficial effects, the large scale application of microwaves in industrial adsorption and catalyst systems has remained limited. Significant gaps still exist in the understanding of how microwaves interact with catalyst systems.

Present research in our lab is focused on the interaction of microwaves with nickel autothermal reforming (ATR) catalysts. These ATR catalysts are used in the production of syngas from gasoline and jet fuel, and have the potential to be paired with a solid oxide fuel cell to comprise auxiliary power units for portable power generation. These catalysts suffer from deactivation due to coking and sulfur poisoning. Catalyst regeneration strategies using microwave radiation are discussed.
