Abstract

The future regulations in greenhouse gases emissions lead the society to find efficient processes for the stabilization of atmospheric CO2. Among the different processes, such as reutilization as an alternative to its geological storage, the catalytic valorization of CO2 methanation, i.e. CO2 hydrogenation, stands as a promising and industrial-scale applicable technology. Although CO2 conversion into methane is exothermic and thermodynamically favorable at ambient temperature, a catalyst and high temperatures (> 350°C) are needed in order to achieve acceptable methane yield. Though many different metals have been used to catalyze the methanation process, the catalysts mostly based on Group VIII metals, such as Ni and Ru mainly supported on porous supports, are the most developed catalytic systems. Ni-based catalysts have been widely investigated, because of their good compromise between activity and economics. In order to decrease the operating temperature for the methanation of CO2, the association of a catalyst with non-thermal plasma have been recently proposed, with dielectric-barrier discharge plasma (DBD), producing a wide variety of active species such as electrons, ions and radicals, improving the CO/CO2 methanation reaction. In this study, we evaluated the coupled plasma DBD – Ni/CeZrO2 system in studying more particularly, the influence of plasma and other operating parameters.
