Abstract
This study presents a novel microwave-assisted dry reforming of methane (MW-DRM) method, significantly enhancing syngas (H2+CO) production at a lower temperature of 400 °C. Compared to conventional heating dry reforming of methane (CH-DRM) processes, MW-DRM achieves higher conversion rates of CH4 (84.6%) and CO2 (85.7%) at a lower temperature of 500 °C, significantly reducing energy consumption. The CsRu/CeO2 catalyst exhibited excellent stability under microwave heating, maintaining high conversion rates and selectivity for 8 h. Detailed characterization using XRD, BET surface analysis, Raman spectroscopy, TEM, and CO chemisorption revealed insights into the structural changes of the catalyst, highlighting the selective impact of microwave heating on the catalyst structure. This study provides a promising approach for sustainable and cost-effective syngas and hydrogen production, aligning with greenhouse gas reduction goals.
