| Abstract Scope |
The use of microwaves in catalysis has shown promising results in increased yields, product selectivity, and energy efficiency. Most reported microwave-driven catalysis is based on small powder beds, and little is known of the effects of scaling the reactions beyond the small fixed beds. This study investigates the use of microwave absorptive and transparent catalyst supports using Lanthanum Strontium Cobalt (LSC) and the catalyst material. Coating methodology was varied along with amount of catalyst deposited to determine the best configuration for larger beds with higher flow rates. Not only was the support material varied, but also the shapes of the supports, including spheres, cylinders, foams, and monoliths. The supports were tested at 2.45 GHz in a fixed-bed reactor and compared against the percent conversion of methane and CO2, along with the energy efficiency. |
