he future regulations in greenhouse gases emissions lead the society to
find efficient processes for the stabilization of atmospheric CO
2
. Among
the different processes, such as reutilization as an alternative to its geological
storage, the catalytic valorization of CO
2
methanation, i.e. CO
2
hydrogenation,
stands as a promising and industrial-scale applicable technology. Although
CO
2
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 CO
2
, 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/CO
2
methanation reaction. In this study, we evaluated the
coupled plasma DBD – Ni/CeZrO
2
system in studying more particularly, the
influence of plasma and other operating parameters.
