Abstract
Steam reforming of acetone, as representative molecule of bio-oil, was investigated over different Ni–Mg–Al oxides with different Ni-environments which were obtained by the preparation of different Ni–Mg–Al materials: Ni-supported, Ni-mixed oxides and Ni like-spinel structures. Physico-chemical characterization of samples showed different Ni-support interactions depending on the nature of the support and the method of preparation. Ni-incorporation into the Mg–Al structure increases its stability. Reforming activity results showed that the Ni-environment interaction plays an essential role on the catalytic behaviour of Ni–Mg–Al catalysts. The sequence of gasification capacity over Ni–Mg–Al samples points out that acidity of supports participates in the acetone reforming mechanism over these catalysts.
