Introduction

Dry reforming of methane (DRM) is a process that uses the greenhouse gases CH₄ and CO₂ to produce syngas, a raw material used in various chemical products. DRM uses a catalyst at high temperatures in a heated catalytic reaction to convert greenhouse gases into useful chemicals and is attracting interest for its potential role in stopping global warming. However, the need for high temperatures, catalyst deterioration induced by carbon deposition, and blockage of the reaction vessel pose challenges for the practical implementation of DRM. Applying an electric field to the DRM catalyst is being studied to lower the reaction temperature and reduce carbon deposition. Catalysis in an electric field involves applying a weak direct current to the catalyst bed, which can result in much lower reaction temperatures. This article describes using the CGT-7100 to quantify the carbon deposits generated by side reactions to evaluate the impact of different catalytic processes on catalyst longevity.
