The dry and oxidative dry reforming of CH4 over alumina-supported CoeNi catalysts were investigated over 72-h longevity experiments. The deactivation behaviour at low CO2:CH4 ratio (2) suggests that carbon deposition proceeds via a rapid dehydropolymerisation step resulting in the blockage of activ...
