dc.description.abstract | The increasing anthropogenic emissions of greenhouse gases (GHG) is encouraging extensive research in CO2 utilisation. Dry reforming of methane (DRM) depicts a viable strategy
to convert both CO2 and CH4 into syngas, a worthwhile chemical intermediate. Among the
different active phases for DRM, the use of nickel as catalyst is economically favourable, but
typically deactivates due to sintering and carbon deposition. The stabilisation of Ni at different loadings in cerium zirconate inorganic complex structures is investigated in this work
as strategy to develop robust Ni-based DRM catalysts. XRD and TPR-H2 analyses confirmed
the existence of different phases according to the Ni loading in these materials. Besides,
superficial Ni is observed as well as the existence of a CeNiO3 perovskite structure. The
catalytic activity was tested, proving that 10 wt.% Ni loading is the optimum which maximises conversion. This catalyst was also tested in long-term stability experiments at 600
and 800°C in order to study the potential deactivation issues at two different temperatures.
At 600°C, carbon formation is the main cause of catalytic deactivation, whereas a robust stability is shown at 800°C, observing no sintering of the active phase evidencing the success
of this strategy rendering a new family of economically appealing CO2 and biogas mixtures
upgrading catalysts. | es |
