Abstract

The influence of nickel particle size in the range of 1.6-7.3 nm on catalyst performance in low temperature CO₂ reforming of methane reaction has been investigated using well-defined catalysts based on a neutral silica support. XAS and XPS studies indicated a reduction degree greater than 90%. The intrinsic Ni/SiO₂ performances were found to be independent of nickel particle size in dry reforming at 773 K using a CH₄/CO ₂ ratio of 1.3 at 1 atm, both at an early stage and in steady state conditions. The H₂/CO ratio was also found to be structure in sensitive but is controlled by thermodynamics through the faster reverse water gas shift reaction.
