摘要：Dry reforming of methane (DRM) is an important reaction to produce syngas via an approach that diminishes carbon footprint but is usually hampered by coking and high operation temperatures. It is highly desirable to conduct DRM in more ambient conditions and preferably produce separate streams of H2 and CO with decreased cost of product separation. While this target seems impossible in conventional thermal catalysis, it can be achieved through the combination of plasma-catalysis synergism and chemical-looping. Herein, we propose a novel plasma-assisted chemical-looping DRM approach. The proposed approach utilizes cost-effective gamma-Al2O3 as the catalyst and can produce separate streams of H2 and CO at room temperature. It was discovered that both gamma-Al2O3 and glass bead packing materials can enhance the methane conversion in the presence of dielectric barrier discharge, a common type of non-thermal plasma. While coke deposition on the gamma-Al2O3 is inevitable, it was found that the coke can be effectively converted into CO in the presence of CO2 and plasma. Depending on conditions, up to 40% methane conversion and 45% of CO2 conversion could be achieved with hydrogen purity up to 80%. This work demonstrates a novel approach for hydrogen generation through dry reforming under room temperature and can be substantially "green" and carbon negative.
