Abstract
Catalytic steam reforming of biomass-derived compounds as furfural could be a promising
option to produce renewable hydrogen; however efficient catalysts are still under study.
Different commercial supports (SiO2, Al2O3, ASA, MgO, MgAl2O3, ZnO, TiO2, Natural Sepiolite)
incorporating Ni by incipient wetness impregnation have been initially tested in the
Steam Reforming of Furfural (SRF). Among them, Ni supported in natural sepiolite
exhibited the best catalytic activity. In order to improve the catalytic performance of this
sepiolite-based catalyst an alternative method for the incorporation of Ni was explored
(precipitation). Precipitation method led to a Ni-based catalyst highly active and selective
in the production of hydrogen. In addition, the production of undesired products (CO and
acetone) decreased significantly. Characterization by BET area, XRD, TEM and TPR shows
that precipitation method allows to synthesize a Ni-based catalyst with higher BET surface
area and smaller metallic nickel particles. These particular physico-chemical properties
seem to be the major responsible of the better catalytic performance exhibited by the
material prepared by precipitation.
