Ab initio calculations were performed on ordered and disordered dolomite and dolomite-II crystal structures. The mechanism for the dolomite to dolomite-II phase transition was investigated by the calculation of vibrational frequencies. In particular, a soft mode was observed at the F point of the rhombohedral Brillouin zone, whose frequency...

In this work we focused on syngas production from bioethanol, achieving proper H2/CO = 2 ratio to feed the FT reaction. The catalysts were constituted by Ni supported over BEA zeolites. The Si/Al ratio was varied to assess the effect of acidity on catalyst activity, selectivity and stability. As well, the effect of Ni loading (0.6–4 wt%) was...
