Dry reforming of methane (DRM)  is an attractive route for sustainable chemical production because it simultaneously utilizes two major greenhouse gases to generate value-added fuels and chemicals. However, conventional DRM typically requires high reaction temperatures to achieve sufficient conversion, resulting in high energy demand and rapid catalyst deactivation caused by carbon deposition.
Non-thermal plasma, particularly dielectric barrier discharge (DBD), provides a promising alternative for methane dry reforming under milder conditions. Compared with conventional thermal or catalytic processes, DBD plasma reactors are relatively simple to construct, scalable, and cost-effective. Moreover, incorporating catalysts into DBD reactors can create plasma–catalyst synergies that improve product yield and selectivity.
In this study, plasma-catalytic methane dry reforming was investigated in a fluidized-bed DBD reactor under ambient conditions. The effects of reactor’s configuration and type of catalyst were evaluated based on CH₄ and CO₂ conversion, product yield and selectivity, carbon deposition on spent catalysts, and catalyst stability during prolonged operation. The energy efficiency of the process was also assessed. In addition, a range of characterization techniques was employed to clarify the role of the prepared catalysts in the plasma-catalytic reaction.
