Natural clay-based Ni-catalysts for dry reforming of methane at moderate temperatures

Abstract Natural clay based Ni-containing catalysts for dry methane reforming (DRM) were prepared using a Fe and Cu-modified Tunisian clay as support. The catalysts were characterized by means of X-ray diffraction (XRD). H 2 -temperature programmed reduction (H 2 -TPR) and CO 2 -temperature programmed desorption (TPD). The catalysts were either reduced at 800 or at 900 °C prior to the DRM tests. Reduction temperature has a determinant influence in Ni crystal size and basicity. The catalysts reduced at 800 °C showed better catalytic performance than those reduced at 900 °C. The catalysts prepared using the Cu-modified clay yielded the highest CO 2 and methane conversions all the time. At 850 °C, 72% CO 2 conversion was measured, corresponding to a H 2 /CO ratio near 1, close to the thermodynamically forecasted value.
