Abstract Herein, the CO 2 reforming of methanol, or can be called dry reforming of methanol (DRM), was investigated for the first time using a rotating gliding arc plasma. The effect of input CH 3 OH concentration on the reaction performance of the DRM process has been investigated. Optical emission spectroscopy (OES) has been used to give insights into the formation of reactive species in the plasma chemical reactions. In addition, the possible reaction mechanisms of the plasma DRM process have been discussed. The plasma assisted DRM has been demonstrated to be a promising route for clean syngas production and high-efficiency CO 2 conversion. This process provided a significantly higher efficiency for CO 2 conversion compared to other plasma technologies, while maintaining a CO 2 flow rate (or processing capacity) of one or several orders of magnitude higher.
